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.

An update on this product. No issues with rust after a season of repeated salt water launching with a subsequent fresh water rinses. I did however notice that one of the wheels blew out and needed replacing. Im not sure why it blew out so quickly. Replacement wheels are sold for just over $5.

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.

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.

Was able to haul the boat very easily in the fall and it was a piece a cake putting it back in the water in the beginning of the spring Highly recommend.

Taking the boat out last fall was a breeze, the rollers worked as said. Putting the boat in the water this spring was a snap. One push and she rolled off.. Highly recommend this product.

They have solved my shallow launch problem. But, a couple of the caps that hold the roller pins have fallen off. I will be replacing them with stainless bolts and lock nuts.

The purchase of these roller bunks still ranks as one of the best purchases Ive made, coming in 2nd to my boat purchase. They are still working as smoothly as they did the day I installed them. They have never failed at any point. I now have both shoulders with torn rotator cuffs, making these bunks my shoulders best friends. I could not imagine launching my boat without them, especially in some of the places I fish.
