Video Transcript for Dutton-Lainson Roller Bunks for Boat Trailers Review

Today on our trailer, we're going to take a look at the Dutton-Lainson boat trailer, Deluxe Roller bunk, part number D-L-2-1-7-4-1, and our five foot section, part number D-L-2-1-7-4-0 for our four foot bunk. Here we are with our boat trailer in the water, and we've got the standard boards. To launch our boat, especially when you're doing it by yourself, can be difficult because you've got to push the boat off. I'm in the water and it's not very easy. But with our rollers installed, the boat simply slides off. You almost don't even need to push it in. Also, just as easy as we launch our boat into the water, it's that easy to load the boat back onto the trailer.

Here's what the complete install's going to look like with our roller bunks in place on our trailer. This'll come with two sets of five foot rollers for a total of twelve sets of rollers. Dutton-Lainson also makes a four foot set of bunk rollers. The four foot long ones are one foot shorter than the five-footers here, and they have one less set of the bunk rollers. Now let's go ahead and show you how to install it. To begin our install, we're going to remove the old manufacturer's boards and brackets.

Since we're removing the bunk boards and brackets, we're just going to take the U-bolts off the frame. Quick tech tip. Before you remove your boards, take a tape measure and get the height of your board. That way, when you install your new brackets and rollers, you can set it back to the same height. Now that we have the boards loose we'll go ahead and take them off the trailer and set them aside, as they will not be reinstalled. For our new rollers, we're going to install a new bracket.

This is the Dutton-Lainson universal mounting bracket, part number D-L-2-1-7-4-2. To secure it to the trailer, we're just going to reuse the old manufacturer's U-bolt. Now once that's set in place I'm going to go ahead and tighten it down. Note for additional security, we can add a second set of U-bolts here on the other side. Now here at the center of support, we're going to have two five-foot rollers come in together.

We'll need two brackets, both getting attached to the same spot. To do that, we'll bring in a U-bolt from each side. This will secure our bracket. Now I've got my first one in place, the back side here of the center support. We've got our second U-bolt and support bracket. Now after all our hardware is in place, we'll make sure she's in position, and then tighten down the U-bolts. Keep in mind when tightening down your U-bolts, make sure you tighten them down evenly. Now once we have the center support done, we'll go ahead and install our last bracket here at the very end and repeat the same process we did for the very first bracket. Now with all our brackets secured, we'll go ahead and put our bunk rollers in place. Starting here at the rear set of bunk rollers, we'll set it onto the brackets first. Now supplied with the install kit, you'll need to add a bolt or bolt and washer for this application that'll go down through your bunk roller, then through the bracket. Underneath, I'm going to add a flat washer and nut. It's recommended to use nylon lock nuts. This will help prevent the hardware from loosening. Let's go ahead and install it finger tight this time. Now we've got our front attachment point in place we'll go ahead and do the same process here for the rear attachment point. Next, we're going to install our front bunk and rollers. It'll sit here on our forward and second bracket. But because of how close we are oriented to the rear bunk, we're going to remove the rear set of rollers and we'll need to drill at our attachment point so that we can secure it to the bracket. Let's start with removing the rollers. Using a couple three quarter inch sockets, we can simply just go ahead and remove the bolt that holds the rollers in place pause. I'm just going to slide the rollers back onto my bolt, thread that nut back on. You've got to hold them together while I set them aside. Now we'll go ahead and put our front bunk in place, set it in position on the bracket, and mark the hole. Now we'll take our bunk back off, we turn it over and drill out the hole. Now to drill out the hole, I'm going to use this small pallet bit and then open it up to my final size using the step-bit process. We're now ready to go ahead and put the bunk back in place, drop in our hardware, and secure it. Now with all our hardware in place, we'll go ahead and tighten down all our fasteners. Now with one side done, we'll go ahead and repeat the same process on the other side. There you have it for the review and install of the Dutton-Lainson boat trailer deluxe roller bunk, part number D-L-2-1-7-4-1.

Boat Trailer Deluxe Roller Bunk - 4' Long - 10 Sets of 3 Rollers - by Dutton-Lainson - DL21740

Average Customer Rating:  4.9 out of 5 stars   (70 Customer Reviews)

D-L roller bunks provide a quick, easy, and inexpensive way to upgrade bunk-style trailers to rollers.

All the materials I received from E-Trailer were well made and easy to install. It was also easy to navigate the website to find exactly what I needed, and the prices were the best I could find anywhere. I highly recommend etrailer. Before and after pictures of my trailer are enclosed 652466

I received the two sets of 4' bunks a little earlier than expected and put them on right away replacing my 8' slick bunks. I used some existing brackets and bought two standard brackets. The alignment wasn't perfect after installing the roller bunks because of the different brackets. After using the new roller bunks once to launch my river Sled in the local river. I had to adjust them a little better. They work awesome now and very happy with the purchase. Like many other reviews say. I wish I would of made the purchase years ago. Way better than the bunks with slicks on them. I have been battling close to record low river flow levels and can't float the boat when launching. Now I give it a push and it rolls right off the trailer in 6-8 inches of water. My home town state owned launch is not in the main river channel ( imagine that ). Once off the trailer we either walk it out to the deep water or use the oars and push ourselves out into the deeper water which is on the other side of the river. These bunks have allowed me to continue to fish the river. I would not of been able to launch without them. The river currently doesn't have enough water in the river to start my outboard and power off the trailer like I have been doing for years. The bunks will pay for themselves by saving wear and tear from sand and gravel while launching on my Jet pump. Just in parts 3 years ago I spent 600 dollars to replace the main components of the pump in just replacing the impellar and bowl. The beauty of it is I can fish anytime now and couldn't be happier about that. What a difference! I helped some other fishermen launch their river Sled the second day and it took all 3 of us to launch it. One in the truck inching forward as the other two pushed the boat off the trailer. Me... I launched all by myself. Very cool! I noticed that some boats have carpeted plywood down the center between the roller bunks. That's the next project for me to do. That way I can launch and reload the boat on to the trailer all by myself without getting wet. Cold season steelhead fishing is just around the corner. Staying dry is important . 433409

The rollers sure make it easy. I put the boat in the water to make for an easy install. Took about 30min. to install the rollers on the new red wood 2x4's and about an hour to install on the trailer. Didn't even have to start the motor to put the boat on the the trailer unlike the regular carpet bunks. So far that is my only use of the rollers but if it was that easy then it can only be a breeze when I actually use the boat. Putting the two sets of 4's together makes for 2 sets of spare rollers if you ever need them. 589744

I mounted 2 - 4' sections of rollers on each rail of my Lund trailer (8' rails). THe installation was easy - I used lag bolts to mount to mount the rollers to the carpeted bunk rails. My Lund aluminum 16.5' fishing boat rolls off the trailer effortlessly. I needed to have this as my launch is very shallow and my trailer doesn't tilt. I consider this to be a wise addition to my trailer as I couldn't push the boat off the trailer with the old carpeted bunk rails (trailer needed to be fully submerged to get the boat off the trailer) 569054

First, the customer service from etrailer.com was outstanding, and the rollers were delivered on time. The rollers are to support a 14-foot flat-bottom jon boat, with no weight of a gas motor on the transom. I saw no need to submerge the trailer to unload or load this light weight boat. Backing the wheels no more than hub-deep in the water is all that is needed for both unloading and loading. I removed the two original 5-foot carpeted wooden bunks and their brackets. The bottom of the boat hull has 5 ribs, sticking down about 3/4”, with about 6 inches of flat space between each rib. Each tripple roller set is just under 5 inches wide, so they fit nicely between the hull ribs and thus guide the hull straight onto the trailer. Knowing that when launching the boat it would quickly roll off the trailer, I attached a cleat to the winch stand to temporarily secure the bow rope when I unhook the winch strap. To load the boat, I attach the winch strap and then move the boat out to the end of the trailer by either walking on the plywood or wading out. Then allign the rib spacing with the rear rollers and winch the boat on. The wood doesn’t get wet; when loaded, the boat shields more than all of it from rain. And I don’t submerge any of the wood at the launch ramp. (Note that carpeted wooden bunks DO get wet when a typical bunk trailer is submerged.) 163223

Having used this product for a year, I still feel the same way I did when I wrote the first review. These roller bunks are great, a quick squirt of spray lube every three or four months keeps everything rolling! A great product.

Arrived quickly as shown on site and the product is as described. The box channel construction appears sturdy. Durometer of wheel seems right for my application, not too stiff, enough flex to provide just a little grip on my varnished wooden boat. Time will tell on performance, install was a snap with a variety of spaced slotted holes for your application. Overall appears to be the proper choice for my application. 391734

Product has worked well, would remain with my positive review and knowing what I know now would buy again. I have recommended the product to others in the past year.

I would give them six stars if I could. These bunks are so easy to install and the quality of them is above my expectation. As soon as you lift the box, you realize these are in fact heavy duty components built to last. I have a bad back and these things take all the stress out of launching and loading! I love these and will install them on all my boat trailers in the future! 333865

Very happy to receive my roller bunks. Shipping was FAST, arrived in 2 days! Opened boxes and found galvanized rails were "beefier" than I had expected. Plan to install them soon on my trailer. I fish my local rivers where flows can get very low during the summer months. Was having difficulty loading/unloading even with glide slicks. These bunk rollers came highly recommended by others as they have them installed on their trailers and these roller bunks solved their loading/unloading issues. 323631



- DL21740
by:

The roller bunks mounted on my trailer's factory weld-mounted bunk brackets without modification. Loading a 4,000 pound plus boat onto the factory trailer with carpeted bunk rails had always required power loading. Now I only need my strap and winch. I only wish that I had switched to these roller bunks years ago. 295672

Easy to install. Work great loading and unloading. Support is good on the bottom of the boat. I used 2 sets-4 ft. roller bunks (4 bunks). The boat is a 16 ft. Smokercraft Pro Angler XL w/ 60 hp Mercury, wt. approx. 1700#. Its a lot easier than with the carpeted bunks, especially when the water levels drop this time of year. The boat will unload itself when you unhook the strap. 215736

These rollers were purchased to mount onto my current bunks, just received them today. After 36 years of being in the maintenance and fabrication field I can tell that these are of good quality and constructed well. They are surely going to make my life a lot easier to get my 20 foot bowrider boat on and off the trailer. I plan to have them mounted within the next few days. 211670

Bolted directly to flat carpeted boards on trailer. Now boat is easily off loaded into water without totally having trailer under water. I have a 18 foot sea ray 185 sport and used 2 sets of rollers on trailer. 208299

They still work great. I pull my boat out of water everytime I use it.The rollers make this possible even at low tied. The rollers are holding up well.

Do you have a question about this Boat Trailer Part?


  • 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.

  • 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.

  • 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...

  • Recommended Bunk Rollers And Hardware For 18.5 Foot Bass Boat

The CE Smith Roller Bunks for Boat Trailers - 6 Rollers Each - 5' Long - 1,500 lbs - 1 Pair # CE27710 will work well for your 18.5 foot bass boat if you use 2 roller sections on each side.

They also said that they are typically used to help as a guide and the bunks normally handle the bulk of the boat and motor weight. I recommend roller bunks like part # DL21741. These are 5 ft long roller bunks that can be attached to your wooden bunks on the trailer or attached to the trailer frame. These roller bunks have a weight...

These brackets allow the roller bunks to be adjusted vertically from the trailer and angled to cradle the boat hull. Neither galvanized roller bunks, # DL21741, and # DL21740, will pivot. But both...

  • Can I Convert Regular Bunks To Roller Bunks

  • Roller Bunk Recommendation for a 10 foot Section of Bunks
  • The longest section of roller bunks we offer is 5 feet like the part # DL21741 that you referenced. For a 10 foot long section you would want to use one 5 foot section like the # DL21741 and then a set of 4 feet long roller bunks like the part # DL21740. The reason for this is that each roller bunk has a roller at the end of it. Since the rollers are spaced 1 foot apart on the bunks you would want 1 foot between each set to equal 10 feet and have the rollers spaced evenly.

  • Bunk Roller Recommendations for a Boat Trailer to Help Boat Load on Trailer
  • Upgrading a boat trailer from wood bunks to roller bunks is a very common modification so the part # DL21740 that you referenced should work very well for you. We sell several keel rollers that would work for you. But you would need to first determine what size you need by measuring the length and diameter of your current one and the diameter shank it is designed to fit so that you can follow the link I attached and pick out the correct size replacement.

I attached a picture of what they look like installed. Or for a 4 foot section the part # DL21740. For install brackets you would want the part # DL21742. You will want to measure the length of your current trailer bunks to determine which size would work best.

  • Roller Bunk Recommendations for a 16 ft Boat Trailer with 8 ft Wooden Bunks
  • Since your current roller bunks are 8 feet in length I would recommend you get 2 sets of 4 foot long roller bunks like the Boat Trailer Deluxe Roller Bunk # DL21740. I would mount them down the middle of the bunks and if you used two sets of the # DL21740 there would be rollers from front to back on your bunks. Although they are not required for installation you may be interested in purchasing Roller Bunk Brackets # DL21742 for installation of the roller bunks.

  • Adding Roller Bunks to a Boat Trailer with 8 Foot Carpeted Bunks
  • What I recommend for you is exactly what you have suggested. Use a total of 2 sets, 1 set of each center bunk, to reach the 8 feet you need. These will secure directly to the tops of the existing bunks. You will not need to replace the bunks. I have included a link to a video review of these bunks for you. The capacity is for a set. So if all the weight was ever on one set of bunks it would exceed the capacity. But since the weight is being dispersed it will not exceed the capacity.

  • Each pair of roller bunks like part # DL21741 and # DL21740 are designed to support up to 3,000 lbs. Adding additional roller bunks raises the capacity which can be loaded on them, Lets say that the gross weight of your trailer is 6,000 lbs fully loaded, fueled and ready to travel.

  • What Roller Bunks Suitable to Replace 8-Foot Bunk Boards on Boat Trailer
  • No special brackets are required to install 4-foot roller bunks # DL21740 on your boat trailer. In fact you can mount them directly to your existing wooden bunk boards. Two pairs of this roller bunk will work great on your trailer to ease loading and unloading of your v-hull boat and your winch will have a much easier time of it pulling up your boat with the reduced friction from the roller bunks. You will want to source suitable hardware, either stainless steel or galvanized, for the...

  • Best Roller Bunks for a 12 Foot Klamath Aluminum V-Boat on a Tilt Boat Trailer
  • An aluminum boat is not going to weigh as much as some other forms of construction so the 2,500 pound capacity of roller bunks # DL21740 is probably going to be enough. But if higher capacity is needed go with the longer 5 foot set, # DL21741 which have a 3,000 pound capacity. Length is also a factor. You want roller bunks anywhere the boat rests on the trailer. Having rollers the appropriate length better disperses the weight of the boat. You can get more than one set and cut to length...

  • Solution for Loading Boat On Trailer Where Nose of Boat Wants to End Up Below Trailer Winch
