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.

D-L roller bunks provide a quick, easy, and inexpensive way to upgrade bunk-style trailers to rollers.Received my 4 foot roller bunks in less than a week, ordering was easy, good follow up, and quality looks to be top notch, can't wait to try them out. 917531
Added roller bunks on my bunk boards and now have easiest launching of any boat I have owned. Have to be careful on steeper ramps to be sure we are ready when bow eye is released - will launch without a push! 899813
We only used them once, but they were invaluable. We have an Eco-Harvester that we have to pull out of our lake each autumn. The launch site is very shallow and the harvester weights about 3,600 pounds. In past years we had to try greasing the wood beams it sits on, but it was always a very difficult job. These rollers worked very well and the winch was able to pull the machine out of the water with minimum human effort. I am going to buy two more sections to go on extension beams further into the water and hopefully start lifting the machine earlier. 854579
This has solved a huge problem I was having with launching my boat. My cabin has a shallow launch and the beds on the trailer were not working. It is a great product!!! 821280

Product, bunk rollers, are exactly what I expected. Will install these on existing 2x6 bunk boards to make it easier to launch or load my 17’ skiff. Product appears to fit nicely and easy bolt-on installation. 747342

Raymond - 10/07/2020my boat never flew into the water so fast and loading it now could be done by a two year old great product made the loading and unloading of my 17.5 ft. tracker a cinch no matter the water levels thanks 694980

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
Great product 650655
High quality material. Works better than expected 640112
I wish these channels were made out of Aluminum due to the fact these bunks are loading a inflatable 10.6 sea eagle. Boy, they are heavy. 610265
Yes sir I received them a day early appreciate everything great product. 598595
I’m in the process of installing them right now. So far it looks like it’s going to be a five star product looks great. I highly recommend this product for boat owners out there 598585
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
