Video Transcript for Dutton-Lainson Boat Trailer Parts - Roller and Bunk Parts - DL21740 Review

Today were going to review part number DL21740. This is the Dutton-Lainson Boat Trailer Deluxe Roller Bunks. These are four foot long. This Dutton -ainson Roller Bunks will provide a quick, easy and inexpensive way to upgrade the bunk-style trailers to roller bunks. This will replace the conventional carpeted bunks in minutes. It will help you load or launch your boat with ease even when the water levels are too low to float on or off.

Theres no need to back into the water until the entire trailer is submerged. Just back to the waters edge and you can roll the boat on or off with the roller bunks. They feature a special non-marking two-compound design rollers, have a durable wear resistant on the inner surface and then a soft-boat cushioning outer surface. These bunks are made of a 12-gauge pre-galvanized steel construction. They can be mounted to any vertical or horizontal position bunk board.

Heres the bottom of it, they do have pre-drilled elongated holes. What you can do is put this on to your current bunk board, drill a hole and attach it down to the bunk board. Now, if you do want to use it, if youre trailer does not have any of the wooden bunks or youd want to use it without the wooden bunks, you can attach them by using this roller bunk bracket that is sold separately. It is part number DL 21742. Basically, what that will allow you to do, has a hole right here that when you go to mount this, since you wouldnt have a wooden bunk to mount it to, you can use the hole on top here.

Mount it to the bottom. And then this would attach to your trailer itself. It has two long elongated holes which youd be able to bolt to your trailer whichever height you need and you do need two of these for each roller bunk. Now again, this one comes with three rollers on each set and there are five sets of three rollers on each four foot length. So youll be getting a this part includes two bunks so youll be getting a total of 10 sets of three rollers and just a couple quick measurements.

I want to show you the lets go back to the overall length. Its going to be four foot long and its going to be two inches wide. And again on the rollers, they are a two-inch wide roller. The total length, in other words, of the rollers will be four and three quarter inches. Now, these roller bunks both of them do have a maximum weight capacity of 2500 pounds. This part is made in the USA. That should do it for review on part number DL21740. .

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

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.

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!!!


Comments
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.

Installed the day I received it. Replaced 3' rollers with these 4's. Easily installed without taking the boat off the trailer. A big improvement over the old ones.Good price and fast delivery!

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.)

Awesome! Worked great for my jon boat. I have them in use for a 16' jon boat mainly to launch on the lake where I live that is very shallow. Even with the heavy boat I can now just give it a shove off and I,m Gone Fish'n:) Take your time placing and adjusting all rollers and be sure to lash down the stern of the boat while trailering. When launching on steep ramps be sure to check that your winch is locked or bow safety chain is secure. I heard of a guy that lost his boat on a ramp and cracked his lower end and hull. Watch out all you Ducks this fall.

will not install for another 15 days or so but product appears to be of high quality....but then have never purchased anything from etrailer that was not well above the norm....

I ordered these bunk rollers to replace the existing rollers on a recently purchased boat and trailer. The replacement rollers look to be better designed with the three roller axles vs the two roller axles. The old set was made from painted steel, which quickly degraded from rust. The new set appears to be zinc coated steel. Time will tell how well these hold up.



- DL21740
by:

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!



- DL21740

Product was delivered in a reasonable amount of time 3 days. Product is as advertised and I have installed quite easily.

Excellent solution for small trailered boats that are just a little too heavy for one or two people to easily handle. This is the answer. Modify your trailer with these to save a lot of grunt work.

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

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.



- DL21740
by:

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.


Comments
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.

WOW... Just wow... I could not believe just how good the quality was considering how cheap the price was... These boat rollers are made very well and the tracks are made with real steel... I haven’t installed them yet but will soon and add to this review... I really can’t see them not doing what they are supposed to do... very impressed and giving a straight no questions asked 5 star rating... Thank you...


Comments
The rollers work perfect.. Quality is second to none... Very highly recommend them if you have a heavy boat and it’s hard to load or unload... Makes life simple..

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)



- DL21740
by:

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 .

great roller, have held up very well, work great, almost to good. Unhook the boat from wench and just touch the boat and it's in the water.

Easy to install when bolting down to old bunk boards. It took me 15 minutes. A very stout product. It did cause the boat to sit higher on the trailer and now it doesn't winch up properly to the front rubber keel wheel. I may have to remove old bunk boards and reinstall with different braces. I'm curious how well these will hold up to salt water with regular fresh water rinses afterwards. This could change the review from good to poor.


Comments
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.

As per the norm, etrailer has hit the nail on the head. The roller bunks are exactly as advertized. Top quaility equipment at a fair price, what more could you ask for. Loading and unloading my 18 skiff is a breeze now. Highly recommend this product and company.

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.

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.

    Roller bunks don't help the water level rise, but they do help with getting a boat on or off a lift.

  • How Much Height To The Bunk Boards Does the Boat Trailer Deluxe Roller Bunks Add
    The Boat Trailer Deluxe Roller Bunks like part # DL21740 will add about 2-1/2" from the height of the bunk board. This should really not pose many issues but you may be able to adjust the bolster brackets or swap them out for a lower profile option. I have attached a list below with some of our replacement bolster bracket options.

  • Does Mounting Roller Bunks on Wood Bunks Lift Boat on Trailer
    Putting roller bunks on top of wooden bunks does raise the height of the boat on the trailer but we have found that you don't need to compensate for that in any other way aside from maybe backing the boat further down the ramp. I'd go with nuts and bolts over lag bolts as they'll be more secure.

  • How Long of a Bunk Roller to Use on a Boat Trailer
    There is not really a rule for the length of roller bunk needed but a good way to select this would be to match them to the length of your bunk boards.

If you need more than you would need to go up a size to the Boat Trailer Deluxe Roller Bunk part # DL21741 which are 5' long and have a 3,000 lb weight capacity. Don't forget the brackets...

  • 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.

    A minimum of two bolts will need to be used to install each Dutton-Lainson Roller bunk part # DL21740 . You can also use the Roller Bunk Brackets # DL21742 to install the bunks. A pair of these are required to install each bunk.

I also recommend using 2 roller bunk brackets like the Boat Trailer Roller Bunk Bracket, Item # DL21742, for each individual roller bunks and removing the wood bunks.
