Today on our boat trailer we're going to review and install the Dutton-Lainson Boat Trailer Roller Bunk Bracket part number DL21742; this is applicable in conjunction with both 4 and 5 foot Dutton-Lainson Roller Bunks part number DL21740 and part number DL21741. To begin our install we're going to remove the old or manufacture's boards and brackets. Since we're removing the bunk boards and brackets we just going to take the u-bolts off the frame. Quick check tip, before you remove your board 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 lose we'll go ahead and just take them off the trailer and set them aside as they will not be reinstalled. Now for our new rollers we're going to have the Dutton-Lainson Boat Trailer Deluxe Roller Bunks part number DL21741. Now for our new Rollers we're going to install a new bracket to secure it to the trailer.
We're just going to reuse the old manufacturer's u-bolt. Once I have it set in place I'm going to go ahead and tighten it down. Note, for additional security we could add a second set of u-bolts here on the other side. Now here at the center support we're going to have 2 5 foot rollers come in together; we'll need 2 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 brackets.
Now I've got my first one in place, the back side here of the center support. We'll get our second u-bolt and support bracket. Now that 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.
It will be the same process 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. Not 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 got our attachment point in place we'll go ahead and 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 going to remove the rear set of rollers and we'll need to drill out our attachment point so that we can secure it to the bracket. Let's start with removing the rollers. Using a couple of 3/4 inch sockets we can simply just go ahead and remove the bolt that holds the rollers in place. I'm just going to slide the rollers back onto my bolt, thread that nut back on; that'll hold them together while I set them aside. Now I'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. To drill out the hole I'm going to use this small poly bit and then open it up to my final size using the step bit process. We 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 do ahead and repeat the same process on the other side. Just like that we've completed the install of the Dutton-Lainson Boat Trailer Roller Bunk Bracket part number DL21742 on our boat trailer.
Heavily constructed and fits the rails perfectly.
Very happy with your product and fast d elivery.
Works like a charm
Arrived in a short time and in great shape. Should work great.
Good product and great delivery timing thanks from Cantu & Sons Alice TX
Product was everything they claimed it would be. Very pleased with the quality and price of the items I purchased.
Received the bunk roller setup as promised and the installation was easy and looks like it was made for the trailer. The installation was fast and all parts worked well. Very happy with the results.
The brackets were easy to install
Would be better if hardware was availab le
like this better than using bunk boards i can adjust the height so that the rollers that center my boat work with bunk board its to high
used horizontally to mount roller bunks to floor of utility trailer
Well made and easy to install.
Roller bunks and brackets are great products.
Its a great design. It was difficult to install - for my application but that was no fault of the bracket design. I was installing them to a boat lift, modified for 2 jet skis, working suspended over water. Add dropping a few tools, nuts and bolts in the water, and it becomes a long afternoon. Haha. I'm sure it would be a simple install on a trailer on dry land.
This proudly sits on a trailer with a Avon inflatable one Honda 20 hp engine the trailer bunkers are now downright slippery
the top of the bracket is peened......slips over to side sometimes when loading and trailering....I replaced with bolt and lockwasher.....still slips......HELP......very poor design
product was eaqsy to install on my trailer. They held the weight load of the boat excellent. Im now ready to go fishing..Thanks alot.
5 Ft roller bunk Part DL21741 is a high quality item. It installed in minutes on existing brackets. Boat is approx 3/4” higher than on standard bunks but it shouldn’t be a problem since it rolls on/off effortlessly. I also bought new brackets Part DL21742 thinking they might allow lowering boat a little but they were same as existing brackets so I returned them which was simple. Customer service was excellent.
Poor design lifts rollers 2 inches higher than 2x4 bunks. Modified everything and had to throw away u bolts
The brackets are as described but unfortunately given my trailer frame I couldn't mount my roller bunks any lower than the standard bunks. The lowest you can get these brackets is probably almost 4 inches above the frame, then you have to bolt the roller bunks on top of that.
used 5 & 4 ft. Deluxe roller bunks. on boat trailer, easy install and boat rolls off trailer very easily. Great product!! Boat is much easier to launch and load.
To keep the same height as the old boards, the backets would need cut and possibly welded to the frame. I raised the bracket just high enough to install the U-bolts. Now, the rollers will not till as designed. Shouldn't hinder loading and unloading but I will see first time out
I used these brackets with the roller bunks and they made installation a breeze paired with the recommended u-bolts. The system literally went together in less than an hour with minor modifications I opted to make. I cannot wait to pick up my new boat and put them to the test.
