Video Transcript for Feature Breakdown: Boat Trailer Standard Roller Bunk

Today were going to review part number DL21754. This is the Dutton-Lainson Boat Trailer Standard Roller Bunk which is four foot long. These Dutton-Lainson Roller Bunks will provide a quick, easy and inexpensive way to upgrade your bunk-style trailers to rollers. They feature a special non-marking roller with a durable wear-resistant inner surface and a soft boat cushioning outer surfaced. This design can be mounted directly to the top of your existing wooden bunks. It is recommended if you do that to use a stainless steel mounting screws.

Itll help in the corrosion resistance. Now also, if you wanted to remove the wooden bunks on your trailer, you can use the optional roller bunk bracket which is part number DL21762 and thats what installs if you remove your wooden roller bunks. Basically, this roller bunk has pre-drilled holes in it so if you go to install this on your regular roller bunk, wooden bunk, you just lay this on top, mark your holes and drill it through and then bolt it to the wooden bunk. If you dont have the wooden bunks or you want to remove the wooden bunks then you can still use these holes but you just use this bunk bracket and basically what that is, it will sit in here and the bolt will go through here and then you can use this bracket to attach it to your trailer with these adjustable slided holes on it. It is recommended to use two of these brackets for each roller bunk.

So in this case, with the two, you will need four brackets. This part is constructed of a 14-gauge steel and has a black powder-coat finish. The rollers on it are free to pivot and they roll to help align with the boat hull. Comes with two rollers and theres five sets for each four foot length so thatd be 10 rollers on each one. And on this part number, you get actually two four-foot bunk rollers.

So that would be 10 sets of two rollers. The combined weight capacity of these two bunk rollers is 2500 pound boat capacity, weight capacity. And again, each roller bunk is four foot long and two inches wide. This part is made in the USA. That should do it for review on part number DL21754.

Dutton-Lainson standard roller bunks - 4' long, for boat trailers.

by:

The order responce was great and the quality of the roller system is excellent and very well made.It will work great on my trailer.



by:

Worked perfect for the hot tub
Needed
a shelf for the cover that I could push on and off by myself



by:

With a little trailer modification that only took about an hour, so far they look and work great. Have not launched in water yet but reloaded the boat from dry ground with no problems. I would highly recommend this product.

Its still working great. The only thing that would improve would be to install an electric winch.



by:

These are heavy duty items. I replaced two wooden bunks with these. I managed to get the screw holes to line up with the existing brackets. I did have to file a hole a bit bigger on one bracket. I decided to adjust all the other 3 rollers on the trailer also, so be prepared for adjusting everything. The screw holes fit 3/8" bolts. They do not come with any bolts. Have not actually used it yet but I can push my 14' boat off and on by hand now.



by:

These roller bunks help me load my boat a lot easier. I guess I was just getting too old to crank it on using the old carpet covered bunks.



by:

Product fits my trailer needs perfectly. It was just as advertised, and the product videos and responses to other writers were very helpful in guiding my decision. I installed the Roller bunks as soon as received and placed them right in service. My hovercraft rides perfectly on them.



by:

I fish the small Ozark rivers, I have a 18' paddle jon and I fish alone sometimes these roller bunks made loading and launching very easy even by myself, now a year later and there has not been a single problem with the bunks I am very pleased



by:

Haven't used them yet but seems like my boat will roll off without the usual struggle



by:

Replaced the bunk boards and could not believe how much easier it is to launch my boat. Most of the lakes i fish in WA state are very shallow and with these rollers i don't need to back my truck in the water to launch my boat.
Very Pleased.



by:

The roller bunks seem to be as represented. They appear to be well made of heavy steel and are nicely finished. Brief but suitable installation instructions and suggestions were included. Though they only arrived yesterday and have not yet been installed, I am expecting years of use out of therm. Three stars only because I have not yet installed or used them. If they perform the way I think they will it will be worth another star or two.



by:

Replaced the drive on bunks on my boat trailer to rollers. Easy replacement. Couple of hours and job done.



by:

I did not use the product for converting a bunk trailer, although it would be an easy conversion. The rollers pivot to adjust to the boats hull which is cool. (I did not realize this when ordering) I made a parking spot for an old fishing boat to get it out of the water yet still right by shore for easy use. The product worked better than I expected for my plan.



by:

Excellent experience! Everything was just as described installed them on the trailer everything works perfect can't believe how fast I got everything! Thank you for your time outstanding service.



by:

My order was shipped the same day and arrived quickly. The rollers look good and are just as described and pictured. I haven't put them on yet but getting my boat on and off the trailer should be a snap from now on and a back saver too.



by:

Exactly as pictured. Installed this weekend, works great so far. Dealing with etrailer was a breeze. Quick to ship, great packing job, couldn't ask for better!



by:

I'm so glad that I've chosen these Roller Bunk!



by:

Great product. Other than a little noisy while trailering, the boat launches much more easily for one person./



by:

The rollers were delivered on time with no damage to the packaging. I've yet to install them but they are sturdier than I thought they'd be. I'll amend this review after I install them and use them but right now I'm impressed.

I have a small 15 aluminum boat that when loaded weighs about 450 lbs. I used a set of these rollers as a one for one replacement for bunks. I was looking for something to make loading the boat easier as Im partially disabled. Best thing I could have done! Great rollers!!! Just be careful launching the boat and dont disconnect the boat until the trailer is in deep enough water to float the boat as it slides off too easy!!! Best mod Ive done to my boat trailer.



by:

made well,easy to put on the trailer,boat loades easy



by:

Extremely happy with product. Installation went very well.



by:

Very prompt service. The Bunk Rollers were perfect for my trailer.
Also very good quality. Will buy again.



by:

Just what I was looking for.
Shipping
was quick thank you

Thank you for your review. The rollers are not designed to line up or center your boat. I recommend to use a boat guide on like part # AR64FR.



by:

Used to build my dinghy dock as I couldn’t find a supplier that had one in stock and a long wait list!. Worked as described, sturdy construction!

Very good product and fast delivery

  • Can Bunk Rollers Act As Guide-Ons on a Boat Trailer
    The # DL21754 Bunk Rollers you mentioned are designed to be mounted onto the narrow end of a 2 x 4 bunk board. If your bunks are turned so that the side of the bunk is in contact with the boat's hull, use the # DL21741 rollers, which would bolt directly to the long side of a 2 x 4 trailer bunk. I used roller bunks on my PWC trailer, and they work incredibly well. Just make sure that you use enough bunk roller units to cover the weight of your boat. For instance, the # DL21754 you referred...

  • Can Dutton-Lainson 4 Foot Roller Bunks be Added to Vertical Metal Bunks
    Ok, I'll go ahead and take these questions one by one regarding the Boat Trailer Standard Roller Bunk - 4' Long- 10 Sets of 2 Rollers # DL21754. 1) Since you have shallow launch areas, adding about 3 inches of height could make it a bit more difficult to launch, so (if possible) it would likely be best to lower your current bunk brackets, if that is how they are attached. 2) You can mount the # DL21754 to your metal bunks since they are vertical. It would be the same practical application...

  • What Prevents Jet Ski From Rolling Forward Off of Jet Ski Trailer with Roller Bunks
    Normally at the front of the trailer where the jack is there's a keel roller like the part # CE32005G for a 2 inch wide trailer tongue or part # CE32003G for a 3 inch wide tongue that the jack pulls the jet ski up to and is held in place.

  • Can the Dutton-Lainson Bunk Board Bracket DL21762 Rotate to Match Hull Angle
    I apologize for all of the confusion. I can tell you with absolute certainty that the Dutton-Lainson Roller Bunk Bracket, # DL21762, will pivot to allow the roller bunk to conform to the angle of the boat or watersport vehicle's hull. The hook piece at the top of the bracket will pivot at the rivet that holds the hook to the mounting bracket. The hook is not easy to rotate because it is designed to have enough tension to hold itself in place once you set it to your desired angle, but a...

  • Should Nuts and Bolts or Screws Be Used to Mount Dutton-Lainson 4-Foot Roller Bunk
    The Dutton-Lainson 4-Foot Roller Bunks, part # DL21754, can be mounted directly to the 2 x 4 bunk boards on your trailer using hardware of your choosing. My contact at Dutton-Lainson advised that the choice of nuts and bolts versus screws is not critical so long as the rollers are firmly secured. I took a few measurements of this part for your reference and to help you select hardware. These measurements are shown on the attached photo. The interior channel for mounting the roller bunks...

  • Can the Boat Trailer Standard Roller Bunks Be Cut Down
    Yes, you should be able to cut the Boat Trailer Standard Roller Bunk part # DL21754 down to three feet long to work on your bunk boards no problem. They do not offer any roller bunks three foot long so the above will be your best option.

    We do have some of the replacement rollers that will work for your vintage 1965 boat trailer, but we do not have some of the rollers you asked about. Thank you for the dimensions. For the very front keel roller I recommend part # YR5213-5. This measures 5 inches long and works with a 5/8 inch diameter shaft. The three center rollers I recommend are part # YR5203-5. These are also 5 inches long and fit a 5/8 inch shaft. We do offer bunk rollers and you can take a look at part # DL21754....

  • Best 5 Foot Roller Bunks for a Jet Ski Trailer
    Yes, we do have a set of 5 foot roller bunks. They are the CE Smith Roller Bunks for Boat Trailers item # CE27710. These bunks have six rollers each, are 5' long, and have a 1,500 lbs capacity. These roller bunks come in pairs and will be perfect for your jet ski. You will also need the CE Smith Bolster and Swivel Bracket Assemblies for Roller Bunks item # CE10003G-4 to attach the roller bunks to your jet ski trailer.

  • Additional Height of Boat Trailer Standard Roller Bunk # DL21754 When Mounted on Bunk Boards
    The Boat Trailer Standard Roller Bunk # DL21754 is going to add 3" of height to the 2'X8" vertical bunks that you have. We do have the Boat Trailer Roller Bunk Bracket # DL21762 that can be used if you feel that the rollers and bunks would raise the boat higher than you would like.

  • Recommended Boat Trailer Parts to Ease Loading in Rough Water and Sand
    For your application I recommend installing roller bunks as well as some guide-ons to help make loading your boat MUCH easier with your conditions. The Caliber Marine Teflon Slides look like they would help to make loading/unloading the boat easier, but not near as easy as it is with the rollers. For the roller bunks we have a selection to choose from and it really just depends on where you plan on installing the rollers. You can piece 2 together for longer boards. From Dutton Lainson...

  • Can Dutton-Lainson Roller Bunks be Installed on Top of Carpeted Wooden Bunks
    You can install the 4' Long Boat Trailer Standard Roller Bunks # DL21754 directly on top of your carpeted wooden bunks (without removing the carpet first). These have a weight capacity of 2,500 lbs per set so 4 roller bunks would be very sufficient for your 2,300 lb boat. Please note that this will raise the ride height of your boat so if that is going to be an issue you can just remove your wooden bunks and mount these roller bunks to the same mounting brackets.

  • Recommended Roller Bunks Replacement for Wooden Bunks for G3 1860 Boat
    We do have a variety of roller bunks that can be used as a direct replacement for carpeted bunks. I recommend either going with the 2,500 lb capacity which comes in Black # DL21754 or Silver # DL21740, OR the 3,000 lb capacity which also comes in Black # DL21755 or Silver # DL21741. I have also attached a link to all of the options that you can check out, as well as a link to all of our brackets if they also need replacing.

  • Solution For Allowing Boat Trailer to Winch In Easier
    The simplest solution may be to install roller bunks on the trailer to help you winch the boat in easier instead of using an electric winch for such a small boat. For a 4 foot long roller bunk we have the part # DL21754 which would be a great option. If you were to use the winch part # DL25200 it would mount to the same mount that your trailer has for it's current winch.

  • Available Lengths of Boat Trailer Roller Bunks
    The only roller bunks we carry, see link, come in 4 and 5 foot lengths. They can be cut to the lengths needed though. So for example if you needed a 9 foot section you could get 2 of the 5 foot models and cut off 12 inches of one to get 9 feet. For a 6 foot section you could buy three 4-foot sections # DL21754 and cut one in half so you would end up with 6 feet on each side.

  • Width of Dutton Lainson Roller Bunk Rollers
    I spoke with the Dutton-Lainson Engineering department, and the rollers are 5 inches wide, outside to outside on the double rollers like the # DL21754. I attached a picture of the dimensions of the triple rollers too which is oddly narrower.

  • Custom Lawn Roller Compatibility Using Boat Rollers To Be Used Behind Mower
    To use the Yates Ribbed Wobble Roller - Heavy-Duty Rubber - 5" Diameter - 1-1/8" Shaft # YR530R-9P for your application, you may want to add the 1-1/8 inch bearings you mentioned and put them on a rod. I've attached a photo of that bearing in the roller wheel. The only other thing I can think of is using a few of the Boat Trailer Standard Roller Bunk - 4' Long- 10 Sets of 2 Rollers - by Dutton-Lainson # DL21754 to create a 4 foot long roller deck you could add weight to the top of.

  • Recommended Roller Bunks for 600 lbs. Boat
    The Dutton-Lainson Boat Trailer Standard Roller Bunk # DL21754 has a combined weight capacity of 2500 lbs. for both bunk rollers. They can be mounted right on top of wooden bunks. Also, if you 'd like to remove the wooden bunks that are likely on your current trailer you will need the brackets # DL21762. You will need 4 brackets to mount the two roller bunks. I've attached the review video of the roller bunks for you to look at.

  • Roller Bunk Bracket # DL21762 Recommendation
    For a roller bunk bracket designed for roller bunks you would want a Boat Trailer Roller Bunk Bracket # DL21742. If you wanted a set of roller bunks for this bracket I would recommend the Boat Trailer Standard Roller Bunk # DL21754. I spoke to my contact at Dutton-Lainson and he informed me that the Slotted Bunk Bracket # DL21584 that you referenced was designed to work on wooden bunks and would not be recommended for a roller setup.

  • Which Roller Bunks Fit Best On 8' Bunk Boards For Lowe 1710 Fisherman Aluminum Boat?
    Since you have 8' bunk boards you will want to select 2 sets of either the Boat Trailer Deluxe Roller Bunks # DL21740 which fits best on bunk boards which lay flat or 2 sets of the Boat Trailer Standard Roller Bunks # DL21754 which fit best on bunk boards which lay on their edge against the boat.

  • Which Boat Trailer Standard Roller Bunks Are Recommended for 6' Long Bunk Boards
    There aren't really any hard and fast rules for the Boat Trailer Standard Roller Bunks. That said, for a six foot long bunk board I recommend using a five foot long roller, part # DL21755. If you wanted to use the slightly shorter four foot long roller, part # DL21754, that could be done as well but you would only need one set. The entire length of the bunk board does not need to be covered with rollers for them to be effective and do their job, just the majority.

  • Recommendations for Bunk Rollers for Jet-Ski Trailer
    Bunk rollers like the # DL21754 you mentioned would be an excellent choice for PWC's that rest on the edges of the bunks, as most of them do. At 4 foot long, they'd probably offer plenty of support, but I'd recommend getting a set that's close in length to your existing bunk boards. A 5 foot long set is also available as part # DL21755. The rollers would simply mount right over the edge of your existing bunk boards, but you'll probably need to remove the carpet from them first. The rollers...

  • Can Dutton-Lainson # DL21754 Roller Bunks Be Used Without Bunk Boards
    In order to achieve their 2500 lb weight capacity, the Dutton-Lainson # DL21754 roller bunks need to be installed to the narrow edge of a 2 x 4 piece of lumber. If the roller assemblies aren't mounted to boards, the weight capacity would be unknown. Granted, a PWC isn't likely to weigh more than 1000 lbs, probably less but because the rollers weren't tested without bunk boards it would be impossible to say how much their capacity would be reduced. I'd recommend simply replacing the bunk...

  • Availability of Replacement Rollers for Dutton-Lainson Roller Bunk Part # DL21754
    Replacement rollers for the Dutton-Lainson Standard Roller Bunks you mentioned, part # DL21754 are available. The replacement roller is part # DL203228. You can see current pricing information by using the provided link that will take you to the product description page. The rollers are held in place by a bolt that runs through the rollers, so replacement would be a simple process.
