Video Transcript for Dutton-Lainson Boat Trailer Parts - Roller and Bunk Parts - DL21741 Review

Today we're going to be reviewing part number DL21741. These are the Dutton-Lainson Boat Trailer Deluxe Roller Bunks. They're going to come in 5' sections, and with this part number, you're going to get 2 roller bunks. Now roller bunks are going to provide a quick and easy way to upgrade your bunk style trailers to rollers. They're going to feature non-marking 2" compound rollers. These are going to feature a durable, wear-resistant inner surface with a soft, boat-cushioning outer surface, so it's not going to cause any damage to the hull of your boat. Now this is a universal mount design, so it's going to attach either vertically or horizontally.

I have one upright and then I have one upside down. That way you can see the bottom surface as well as the mounting locations. Now each bunk is going to contain 12 mounting slots. It does not come with hardware. The instructions recommend using 3/8" cap screws, flat washers, lock washers and nuts, or 3/8" lag screws for mounting to wooden bunks.

There's also an optional roller bunk bracket. It is sold separately. You can find that on our website with part number DL21742. Now it's going to contain 12 sets of three rollers. You can see they have a nice, rolling design so it's going to allow you to easily get your boat on and off of your trailer. It's going to be constructed of 12 gauge galvanized steel, and Dutton-Lainson's going to make this product here in the USA.

Now, again with this part number you're going to get two roller bunks. The bracket width is going to measure 1 7/8". The bracket height is also going to measure 1 7/8", and wheel to wheel width is going to measure 4 3/4". This unit is going to have a capacity of 3,000 pounds. That's with the two bunks combined.

That's going to do it for our review of part number DL21741. This is the Dutton-Lainson Boat Trailer Deluxe Roller Bunks.

I installed the 5' roller bunks on my Seadoo trailer, and they make loading and unloading a breeze even with shallow ramps or if the tide is out. I drive on, throttle up and hook the bow eye. So far they have not rusted, but it's only been one season. 433210


Comments

Season 2 is now behind us, and the roller bunks are still rust free and working as new. As far as I can tell from normal use With that said, I only used it a few times this year in fresh water.

I received the roller bunkers but had to wait a few weeks to install them and try them out. I put the 5' roller bunks on 8' carpeted, wooden bunks as your instructions suggested (centered). Once I had the hardware it was a simple process. I took my boat out of the water and could not believe how much easier it was. After I serviced my boat I put it back into the water. I basically had to hold the crank handle to keep the boat from sliding into the water too quickly. I am so pleased with this product, and the best part...I didn't even get my truck tires wet. 122263


Comments

Did you have to adjust the height of the 8 bunk board and where on the bunk board did you install them? Front, middle, or the back?Dave

-- comment by: Dave - 05/10/2014

If you go with roller bunks that are less than the length of the wood bunks, then you need to center the rollers on the wooden bunk. On this boat trailer, there were only the two bunks and each got a set of rollers so no height compensation was needed. The only time you will need to adjust bunk height is if you are not putting rollers on all of them.

I have been looking for a method of easily storing a light fishing boat (Coleman Crawdaddy) on a floating dock. When I saw pictures of your boat trailer rollers I thought that they would work well. The boat is about eleven feet long and weighs between 250 and 300 pounds depending on the amount of gear. The floating dock is about 14 inches above water level. I installed a pair of four foot and a pair of five foot rollers to make a nine and a half foot bed. I screwed the rollers directly into the treated decking of the dock. The system works very well with the boat launching and landing with ease. The rollers are of very good quality, were delivered promptly, and arrived in excellent condition. I am very well pleased with the product although I am using it in a manner different than for which it was designed. Your web page pictures and technical data were also of great help in the planning. 19999

Combined bunk rollers and a keel roller (along with a winch and some lumber) to create an easy way to lift and store our 22' kayak. Works like a dream! 555096

No more replacing old rotten wood bunks and recarpeting. Problems YES!!!!!, but not with installation of rollers. Bolts were all rusted and of course would not loosen sooo a large screwdriver and a hammer to split the rotten wood and then a hacksaw and vicegrips to cut the bolts I started installing the outboard 5ft rollers first nooo problem, then the inside 10ft rollers (I bought 2ea 12" pieces of 1/4" angle iron for the center brackets where the 2ea 5' rollers would attach and now I'm ready to drill my holes but, the 2ea new 18 volt batterys are both dead (I just charged them both the day before) luckly I had my doz-all saw with me but, I had been using it to trim tree branches and it showed only 1/2 a charge left. Take a chance or leave the boat in the lake over night. (Now my wife wants to know just how much longer is this going to take) I live 75 miles away. I needed to drill 4 holes through 1/4" steel. I thought I would give it a try until the battery has nothing left. Thank God I had sharp drill bits (3 different size bits for each hole) Just as I was finishing the last hole, again I hear HOW much longer!!!!! Well the rollers look great and work great!!!!!! Much easier to launch, and when trailering I don't need to back into the water as far and, they center the boat better when putting the boat on the trailer. This is the second trailer that I have put rollers on. (I didn't have this many problems and my wife wasn't there). If you're thinking of changing to rollers I'm sure you'll be happy, just be prepaired with every thing you need and give yourself time about 1 1/2 hours and, if its hot - - you might think about leaving the wife else where!!!!! I should have had my wife take pictures. Sorry about that!! 209833

Received 3 business days after order. Quality is excellent. Install was simple using 3/8 X 2 inch "lag screws" and washers over carpeted bunks. This was for a 14 ft Lund boat that I use in shallow lakes that do not have deep water ramps and many times the boat is not in the water when unloading. Boat loads and unloads easily now. Would recommend. 201035

perfect for this float on trailer. I'm trying to solve that this trailer has 8 foot bunks? I i have no other choice but to bolt them on top of the wood bunks. It is a nice well made product. my boat is only 19 foot by 6 wide. this trailer is overkill. with this roller bunk I will like it even better! thanks! 287586

Just wanted to brag on Papa's amazing boat ramp, built by his own bare hands, all in the name of fun. Behold and bask in it's glory! The rollers work very well and all I lack in finishing the job is some stain to make it look professional. 23620

It was so much easier to unload or load the boat back onto the trailer. If the boat is not all the way on I would hook up the winch or safety chain and pull the boat trailer out of the water and then finish pulling it to the bow stop. It moved very easy. 561135

First off, I alway wanted a set of these, but couldn’t justifying installing them when there was nothing wrong with my stock bunks, and my boat was never a issue to put on/off the trailer. WAS I EVER WRONG!!! I have an 2014 Lund WC-14 that spends most of it’s life on my trailer. It is used in fresh and salt water and always well rinsed after use. A short while after putting it in the water for the first time this year, I noticed a pin hole leak in the hull. The boat is in show room condition, so I couldn’t believe my eyes. When I got it back home, I pulled the boat off the trailer to find that the aluminum hull was starting to pit where the trailers carpet coated bunks make contact. Everywhere else was still like new. After fixing the hull with JB weld marine, I had to find a way to prevent this from happening again. The only answer was to use a bunk that does not hold moisture. After doing some research, I decided on the 5’ Dutton-Lainson roller bunks. Super easy installation using the same mounts as the old carpet bunks. I pulled off the old bunks and bolted these to the old brackets. I did have to lower the mount brackets to keep them at the same height as my old bunks. No big deal. Less than a hour later, done. I can roll the boat back and forth on the trailer with one hand now, and moisture should not be a problem. 557588

Fantastic service and follow up. I got an email right away thanking me for the order, and then another email later that day letting me know it had shipped and giving me my tracking #. Those were just the "auto reply" notes - when I sent a quick note saying "Great service as usual", it opened up an email conversation with George J. who suggested I write a review, so here I am. The quality of the materials and engineering is unbelievable - 38 lbs. of steel and rubber for $113. We were going to build something like this... until I saw these babies and the price, and to make it better, they got here in 3 days!!! Our application is pretty unusual. Every Spring, we haul several snowmobiles up into the loft of our garage to get them out of the way for the Summer months. It's a 14' vertical lift, and the sleds weigh 550 lbs. Lifting them with a winch is the easy part, but the challenge was how to move them sideways once we got through the hatchway in the floor. These bunks were the perfect solution. Once the sleds clear the opening, we slide two 2 X 8's over the opening, roll the bunks out onto the 2 X 8's, lower the sled onto the bunks and simply pull it sideways. It is now a one person job, and everyone that watches this process is amazed. Thanks etrailer !!! 233686

Installed these on my existing boat ramp. I poured a 'V' groove like a curb and installed. At the top I installed a 3 ton winch. I pull my 28 foot pontoon boat out of the Gulf of Mexico no problem. I enjoy watching the neighbors eyes light up in envy. Great product and easy to install. One note: I shoot them with white lithium grease regularly due to being in the salt climate. 258300

Just got the package, there are in fact two sections of 5' rail in each box. I ordered two, because I really needed 20', but I wasn't sure what I was going to get (description could have been better). I'll install on my bunks this weekend and see how they work. My bunks are in a V shape, so i'm thinking the boat will skid a bit coming up the bunks - If this is a problem, i'll cut the sections up and mount them latterally. Quality is B - rollers are a hard rubber, more like a hockey puck, which might make the skidding easier. BTW, this is going on a trailer for a 1977 Master Craft - the trailer is a piece of junk - and I think these rollers will make it a useful peice of junk. 51049

I ordered the bunk rollers to make launch and recovery operations possible or easier on some of the shallower boat ramps in my area. The boat is an aluminum 24' model that weighs about 3500 lbs. I had 10' bunks so I ordered 2 sets of rollers. They were shipped on time, arrived a day or 2 early, and installed without a hitch (you will have to order or provide your mounting hardware) . With only one trip on the trailer with the new rollers installed, I have been very pleased and look forward to the fishing season being more enjoyable. I am a repeat customer and have ordered everything from trailer lights to tandem stainless steel disc brake kits and have not once be anything but satisfied with etrailer staff and service. Keep it up. 358465

This roller set works great but it does bend if the boat is not properly aligned when getting the boat back on the trailer. All in all a great product and makes my whole operation alot smoother. 610886


Comments

Each pair of rollers has a 3000 lb capacity, which would be 1500 lb per roller bunk. If the boat isnt properly positioned, the capacity of one of the bunks can be exceeded depending on the size of the boat.

I built a double JetSki trailer and needed bunkers. So after considerations of lastability, durability and ease of use I decided to go with roller bunks. My first Jetski I purchased I had to actually pick up off the ground but the strap on the either Jetski and simply started cranking. With the roller bunkers the ski got right on this is with one man picking up unit with nothing but a strap!! This wasnt a kids 1500cc Jetski laying on the ground either I simply cranked & rolled it straight up onto the bunks no problem! Since this time I’ve had orders of 12 trailers to be manufactured! Ill never have to replace boards or carpet or worry about them breaking in travel and crushing hulls! Love it 601606

These items are as described on the web page. Very good quality with all components included. This has been my experience with every item that I have purchased from ETRAILER. Items that are properly designed for a purpose, built with quality, for easy installation, durability for the intended use, and while maybe not the best price that is available, it is a fair price that's built as advertised. I will continue to buy from them as I trust what I am buying. Very good company. 590780

These rollers are incredible! Very well built, solid steel and substantial nylon plastic rollers. We are harvesting seaweed in Maine into a 24' Carolina skiff on a wooden bunked trailer and we had a hell of a time getting the boat up onto the bunks. With these rollers we save a ton of time trailering on and off the landing. Our boat and load of seaweed weighs in at 4 tons! These are like MEGA-ROLLERBLADES for your boat hull! Hardly back into the water anymore! Just get the transom floating and kick the winch into free-wheel - boat slides off like a kid on a slippy-slide - amazing! Thanks etrailer and especially Donna for her great customer service! 569090


Comments

Were glad youre happy with the bunk rollers! They do indeed work great! Be aware that each set of two has a 3000 lb capacity. Exceeding that weight rating could damage the roller assemblies and cause damage to your boat.

  • Roller bunks can make loading your boat on its trailer a lot easier and can also take away much of the stress on your winch by substantially reducing friction between the boat and trailer. Adding rollers to the trailer will not extend your trailer's reach into the water but it will make it easier to get the boat loaded once it reaches the rollers.

These brackets are held to your trailer with u-bolts like the CE Smith U-Bolts - Galvanized - 3-13/16" Long x 3-1/16" Wide x 1/2" Diameter - Qty 4 # CE15283GA-4. These brackets hold on your Bunk boards like the CE Smith Carpeted Bunk Boards for Boat Trailers - 6' Long - 1 Pair...

  • Recommended Roller Bunks or Roller Bunk Wheels for Boat Trailer
  • The CE Smith Wobble Roller for Roller Bunks - 2-1/2" Diameter - 1/2" Shaft # CE29566BULK is a strong product and is well made. The Dutton-Lainson roller bunks like # DL21741 are also very well made with a current 4.8 out of 5 star rating. The CE Smith Roller Bunks for Boat Trailers - 6 Rollers Each - 5' Long - 1,500 lbs - 1 Pair # CE27710 have 5 out of 5 star ratings but from far less people. They are both excellent products. The roller bunks have 18 wheels each so I think the price...

  • Compatibility of Boat Trailer Roller Bunks with CE Smith Swivel Bracket Assemblies # CE10196G-4
  • If your Dutton Lainson roller bunks have a flat bottom surface like part # DL21741 then you can mount them directly to the CE Smith Bolster and Swivel Bracket Assemblies # CE10196G-4 as shown in the linked photo. These are the tallest ones we offer. If the bunks have an open channel in the bottom, like part # DL21755, then you will want to first mount the bunks to a 2 x 4 bunk board which will fit into that channel and then mount that to the brackets.

  • Distance From Top of Roller to Frame for Dutton Lainson and CE Smith Roller Bunks
  • I believe you are asking about the height from the top of the roller down to where the bracket would mount on a trailer. The # DL21741 is 2-1/2 inches for that dimension and then the # CE27710 is 2-13/16 inches. These are both hot dipped.

  • Recommended Fulton Winch and Roller Bunks for Ram-Lin Single Axle Trailer with Wooden Bunks
  • Trailer winches, like trailer jacks and hitches, are best selected to provide a healthy safety margin in their weight capacity. All such items tend to last longer and work better when they are not operated at their limits. For a boat that weighs in the range of 2700-lbs you want to choose a winch that offers at least half that weight in pulling capacity. The Fulton F2 # FW32000101 is a 2-speed enclosed winch rated for 3200-lbs. This includes a strap and a nice feature, an adjustable...

  • Can 5 Foot Roller Bunks Replace 7 Foot Wood Bunks
  • Most likely yes, but that really depends on how much of your wooden bunks your boat is using. A lot of times bunks are longer than needed so if the front of your boat isn't using the full length of the bunk you could easily go with a 2 foot shorter section of bunk like the part # DL21741.

  • Roller Bunks for a Boat Trailer with 7 Foot, 3 Inch Long Bunks
  • What I recommend is to use 2 sets of the roller bunks # DL21740. Two bunks can cover the length of one bunk but you will need to trim one to fit. One set would be needed per bunk and then trimmed to fit. One roller bunk alone is 4 feet long. Normally I would say to strategically space them but a 3 foot, 3 inch gap is a little too much to overcome with strategic spacing.

  • Recommended Roller Bunks to Replace 7 Foot Bunks on Boat Trailer
  • I spoke with my contact at CE Smith and she stated that 5 foot roller bunks will be adequate for your 15-1/2 foot Smokercraft Alaskan, as long as the space between the cross members are 56 inches or less. If the space is more than that, the 5 foot long bunks will not be enough and you can then obtain two sets of 4 foot bunks and have them cut to size. For a 5 foot long roller bunk, I recommend the CE Smith Roller Bunks for Boat Trailers # CE27710. This is a channel-style roller bunk...

  • Comparing Dutton-Lainson and CE Smith Roller Bunks
  • There isn't a whole lot of difference between Dutton-Lainson roller bunks # DL21741 and CE Smith roller bunks # CE27710. Both have 5 foot long sections. Each section is rated for 1500 pounds. There are 6 rollers per section on both. Both are made with galvanized steel and heavy duty black rubber rollers. The main difference besides price is the shape of the rollers is not exactly the same. Either set can be mounted on a bunk or independently. To mount independently you would need...

  • Trailer Roller Bunks and Keel Roller Recommendations for a River Raft
  • It sounds like you are looking for roller bunks such as # DL21741. These are 5 foot long sections (2 in a package) and are the longest we have available. Each section has 12 sets of rollers. They can be mounted directly to a wooden bunk or to the frame by using bracket kit # DL21742. If you are looking for a keel roller we have a 5-1/2 inch model # YR5244-105EC but no 6 inch. The next size up is 8 inches. With it you can use shaft # CE10722A with brackets # CE32004G or # CE10301G.

  • Roller Bunk Recommendation for a Boat Trailer With 8 Feet Bunks
  • Yes, you would want to use two sets of 4 foot roller bunks since your current bunks are 8 feet long. I would recommend you go with the Dutton-Lainson Boat Roller Bunks # DL21740. These roller bunks would have plenty of capacity and would be sized perfectly. I attached a review video for this product for you to check out also. You may also be interested in purchasing Roller Bunk Brackets part # DL21742.

  • Recommended Trailer Winch for a 29 Foot Sea Ray SLX with Twin 350s on a Triple Axle Trailer
  • Sounds like a pretty nice beast of a boat you have! I would recommend the Dutton-Lainson Marine Electric Winch # DL25200 for your Sea Ray SLX, because of its 4,000lb capacity. Winch capacities vary depending on the nature of how they will be used. Factors such as the type of bunks on your trailer (rollers versus carpeted bunks), the amount of incline, the length of the winch cable or strap all affect the actual working capacity of a winch. Boat-size-to-winch capacity is generally 2...

  • A minimum of two bolts will need to be used to install each Dutton-Lainson Roller bunk part # DL21741. You can also use the Roller Bunk Brackets # DL21742 to install the bunks. A pair of these are required to install each bunk.

  • Recommendation for Adding Bunk Rollers or Replacing Current Bunks with Rollers on Boat Trailer
  • Assuming that your bunk rails are at least five foot long, I would recommend using the Dutton-Lainson Boat Trailer Roller Bunks, # DL21741. This system includes 2 - 5ft sections with a 3,000 pound weight capacity and offers universal mounts to attach either vertically or horizontally. This bunk system can be mounted flat against your current bunks and it is recommended that you match the length of the rollers to the length of the bunks. You will want to ensure that your bunk boards are...
