Website is easy to navigate. Product came to my door within just a few days. The bunk rollers are the perfect solution to getting my boat on and off when the tide is so low there is not much water on the boat ramp. Thank you etrailer.... 522465

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

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

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

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.

My boat trailer had carpet covered bunks. When loading my boat, an Aqua Craft 24,about 3000 lb, the bow would hit the stops at the winch but when I pulled the trailer out of the water and the boat settled on the bunks the difference in angle would leave the bow about 4" from the stop at the winch. sitting on the carpeted bunks I could not pull it up to the stops. I removed the bunks and replaced them with the Deluxe Roller Bunk. The boat rolls easily up the the stops now and will roll off into the water. 905249

To me, instructions are not necessary as the hole-patterns on the Roller bunks are perfect to fit many models of Trailer. It was a fairly simple process. Remove the Board bunks and install the Roller bunks directly on the supports used for the Boards. 785170

Ask the Experts about this Dutton-Lainson Boat Trailer Parts

  • Boat Keel Is Cutting Keel Roller When Launching Boat
    It does look like the weight of the boat may be too much for the keel rollers that you are using from the photo which is why the keel is digging into the roller. You could replace the rubber keel rollers with plastic like CE Smith Keel Roller for Boat Trailers part # CE29516 if your bracket is 5" wide with a 5/8" diameter shaft. The plastic construction will do a better job at supporting the keel. Ideally the trailer would have another cross member to add another keel bracket assembly and...

  • Can Carpeted Bunks Replace Roller Bunks on Boat Trailer to Make for Easier Launch
    Roller bunks will make what you are trying to do incredibly easy as the boat will basically want to roll off on it's own and not require you to push it off. So without knowing what length your bunks are overall you have a few options to get the best length setup. You could use a combination of 5 foot sections like part # DL21741 and 4 foot sections like part # DL21740 to get the best length possible. These even could bolt directly to your carpeted bunks for an easier install. Or we...

  • Recommended Roller Bunks for Boat Trailer to Ease Launching and Loading Boat and Bunk Guides
    The best option for your boat to move better on and off your trailer is to use the Dutton-Lainson Boat Trailer Deluxe Roller Bunks # DL21741. These rollers make loading and launching your boat easy. They are available in 4 and 5 foot lengths, so I've linked a page to assist. You will also need the roller bunk brackets like # DL21742. The attached video will also help you with the installation and operation. One note is that we recommend having a rope attached to your boat when using...

  • Roller Bunks Needed for Boat Trailer Carrying a 2014 Tahoe Q7i
    We do have roller bunks that you can utilize on your boat trailer! For your 10' bunks use 2 of the 5' long bunks, part # DL21741 or # DL21755, and then use 2 of the 4' lengths # DL21740 or # DL21754 for your 8' bunks. just be mindful that the 5' long rollers have a weight rating of 3,000 lbs and the 4' long rollers have a weight rating of 2,500 lbs. All this means is that you don't want more that that much of the 2014 Tahoe Q7i's weight resting on a single set of the rollers at one time.

  • Recommended Roller Bunks for 2020 18 Express Boat with Back Track Aluminum Trailer
    The best option in my opinion is to use the Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections - 12 Sets of 3 Rollers # DL21741 which will allow you to angle the set farther up the trailer to help you center the hull but I recommend using a keel roller like the CE Smith Deep V Keel Roller Assembly for Boat Trailers - Galvanized Steel/Black Rubber - 5" # CE10401G to help center the boat.

  • Can Roller Bunks Replace Wooden Bunks on Boat Trailer Using Same Brackets
    Yes, you can attach roller bunks in place of wooden bunks like with the part # DL21741 as the brackets of both designs are the same typically. I attached a review video for the roller bunks for you to check out as well.

  • Parts Needed to Add Roller Bunks to Boat Trailer
    Probably the easiest way to mount rollers would be to use # DL21755 which would slip onto the existing wood bunks and be bolted into place. For a keel roller, I'd recommend # CE10401G and the proper u-bolt kit, depending on the size of your cross member. For a 3 inch cross member, # CE15283GA-2 would be ideal. The # DL21741 roller bunk you'd looked at would also work, but you'd need brackets like # DL21742 and u-bolts like what's mentioned above.

  • Roller Bunk Recommendation When Additional Length Beyond 5 Feet is Needed
    The longest roller bunks we offer are 5 feet in length like the part # DL21741. What most people do is determine how long of a setup they need and then use more than one bunk to add the additional length. For 4 foot sections we have the # DL21740 as well. In the picture I attached you can see a boat trailer that uses two sets to create additional length.

  • Weight Capacity of Boat Trailer Roller Bunks Explained
    The weight ratings for roller bunks like the Dutton-Lainson Boat Trailer Deluxe Roller Bunk - 5' Long Sections # DL21741 are interesting as it was explained to us that the capacity listed (3,000 lbs) is the max weight that the boat can be regardless of how many roller bunks are used. So if your plan is to use roller bunks and you were going to use the # DL21741 the capacity would be 3,000 lbs. This is due to the fact that at any given point a single set of the rollers could be carrying...

  • Can 5 Foot Long, 3,000 Pound Capacity Roller Bunks Support a 5,000 Pound Boat
    The capacity per set of roller bunks, # DL21741, is 3,000 pounds. A 5,000 pound boat would be too heavy even though not all of the weight would be applied to all of the rollers all of the time. You would need additional support to ensure that nothing fails. Additional rollers placed side by side could be one solution. The rollers can mount directly to a flat bunk or you can use brackets, # DL21742 (4 per pair of rollers).

  • 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.

  • How to Attach Roller Bunks # DL21741 to 6 Ft Wooden Bunks on a Boat Trailer
    You are correct, you can mount the Boat Trailer Deluxe Roller Bunks, item # DL21741, directly to the top of your existing wooden bunks. If mounted in this fashion you would not need any brackets. I would recommend stainless steel mounting screws, available at a local hardware store, to attach the roller bunks to your wooden bunks. If you wanted to remove the wooden bunks, you would need to use the Boat Trailer Roller Bunk Brackets, item # DL21742, to install the roller bunks on. I...

  • Roller Bunks for a 1998 19ft. Carolina Skiff Boat Trailer
    You should not have any problems using 2 sets of the Deluxe Roller Bunks end to end on the bunks on your trailer. I checked out some photos of the 19 foot Carolina Skiffs online and found that the bunks are normally made from what looks like 2x4 lumber laid flat. This means that the original bunks would be about 3-1/2 inches wide, and the roller bunks, # DL21741, are 4-5/8 inches wide overall, see attached photo, so they will support the boat on a wider portion of the hull.

  • 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.

  • Mounting the Dutton-Lainson Boat Trailer Deluxe Roller Bunk on Boat Trailer
    The Dutton-Lainson Boat Trailer Deluxe Roller Bunk # DL21741 is designed to attach directly to 2 x 4 bunk boards so it will may work for your set-up, but I recommend instead to mount the roller bunks with the Roller Bunk Bracket # DL21742 and U-Bolts # CE15283GA. This will give you roller bunks that are certain to work; you can see the simplicity of how this set up will work in the accompanying photo. I've also attached links to video reviews of these parts for you to take a look at.

  • 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...

These roller bunks can be attached directly to a flat surface or you can use bracket # DL21742 (4 needed per set). We also have carpeted bunks, 4 feet long, all ready to be installed, # CE27810. Carpeted bunks have more resistance though than rollers. To mount these you can use bracket set # CE10000G-4 per bunk...

  • Bunk Roller Recommendation for a 22 ft Trophy Boat that weighs 5,000 lbs
    The capacity per pair of Boat Trailer Deluxe Roller Bunk # DL21741 is 3,000 lbs. If you used two pairs and the weight was evenly distributed you would have a capacity of 6,000 lbs. However, these rollers are 5 feet long so if you used 2 sets you would have 10 feet per side. For a 4 feet sections you would want Boat Trailer Deluxe Roller Bunk # DL21740. However, these sets only carry 2,500 lbs of capacity per pair, so if you used two sets you would be at 5,000 lbs which is what you listed...

    The Dutton-Lainson Roller Bunks, # DL21741, do not have to start at the beginning of the stern. To install the roller bunks on your 6 foot bunks you could mount one 5 foot section on your bunks and leave 6 inches on each end. The 5 foot roller sections require two Dutton-Lainson Roller Bunk Bracket, # DL21742. You will also want to make sure that the roller bunks will be able to handle the weight capacity of your boat.

    Most boat trailer winches, whether manual or electric, use standardized mounting. The linked photo of the bottom surface of this Fulton electric winch shows the T-slot mounting scheme. This matches up to a plate such as the Dutton-Lainson Mounting Adapter Plate # DL24055. The winch mount must be capable of handling the full capacity of the winch. For a trailer, you really should have a secure mount such as a steel plate welded to the trailer frame. I suggest you have a look at the...

You can use your own hardware to secure the rollers to your existing bunk. There are holes in the base of the roller frame to do so.

  • Roller Bunks for a 3,000+ Pound Sailboat and Boat Trailer
    For your sailboat I recommend using roller bunks # DL21741. But since the set is rated for a maximum of 3,000 pounds you will need to double up rollers. So for example if the trailer had 5 foot long bunks you would need 2 sets of rollers for each side to account for the total weight of the boat. that is what you would have to do for larger boats. Even if not all of the weight is on the rollers all the time it is still a good idea to err on the side of caution and use additional roller...
