Quick delivery by etrailer. Excellent quality roller set. Very sturdy. I'm sure it will last for years. I just wish they made an aluminum version so my jetski beach-skids would be lighter.36812

Just wanted to brag on Papa's amazing boat ramp, built by his own bare hands, all in the name of fun. Behold and bask in it's glory! The rollers work very well and all I lack in finishing the job is some stain to make it look professional.23620

I received and mounted it on my boat trailer today. I was happily surprised at the heavy weight and construction. I can honestly say it is better than I expected. Now instead of the fight I sometimes had with friction on the flat bunks, I now will be careful about how easy the boat slides. These roller bunks will work great with the shallow water conditions where I live. Most of the time the trailer is not deep enough to float the boat on or off. Obviously off was the hardest.76586

I installed these roller bunks and have already found that I can move my boat around on the trailer much easier. With the old carpeted bunks, I had to have the trailer submerged to where the boat came up to the bow stop. Now, I should be able to winch the boat up the last two or three feet and it will make loading much easier.65150

Just got the package, there are in fact two sections of 5' rail in each box. I ordered two, because I really needed 20', but I wasn't sure what I was going to get (description could have been better). I'll install on my bunks this weekend and see how they work. My bunks are in a V shape, so i'm thinking the boat will skid a bit coming up the bunks - If this is a problem, i'll cut the sections up and mount them latterally. Quality is B - rollers are a hard rubber, more like a hockey puck, which might make the skidding easier. BTW, this is going on a trailer for a 1977 Master Craft - the trailer is a piece of junk - and I think these rollers will make it a useful peice of junk.51049

Very heavy duty construction, I used the rollers to construct a ramp to pull our Jet Ski out of the water. When I priced pre-assembled ramps or floating docking systems the prices were about 2K and for about two hundred dollars I have a system that works just like the expensive systems thanks to the bunk rollers.49757

I used these for runners on my boat trailer, and they worked great. I have a flat bottom boat, and the trailer is home made, that had two 4x4's for runners on it. So I bolted these roller on top of the 4x4's & now I have no problem winching up my boat in place. I am very happy with these rollers. 40017

I have been looking for a method of easily storing a light fishing boat (Coleman Crawdaddy) on a floating dock. When I saw pictures of your boat trailer rollers I thought that they would work well. The boat is about eleven feet long and weighs between 250 and 300 pounds depending on the amount of gear. The floating dock is about 14 inches above water level. I installed a pair of four foot and a pair of five foot rollers to make a nine and a half foot bed. I screwed the rollers directly into the treated decking of the dock. The system works very well with the boat launching and landing with ease. The rollers are of very good quality, were delivered promptly, and arrived in excellent condition. I am very well pleased with the product although I am using it in a manner different than for which it was designed. Your web page pictures and technical data were also of great help in the planning. 19999

• Tips on Loading a 2004 FourWinns Model 194 FunShip Boat Onto a Trailer From the Water
  
• The key to launching a boat into the water from the trailer is to know how far to back the trailer in. It takes some time to get used to, and different ramps may require you back more or less in, but once you have it figured out it should be easy. The winch you are using may not be rated high enough for the boat. With the trailer back into the water at the right spot, the right winch should not have trouble pulling the boat since part of it will still be floating. A 3000 pound capacity winch,

• Can Boat Trailer Deluxe Roller Bunks Be Used with a Tr-Hull Boat
  
• I believe the issue is that on a tri-hull boat, too much of the boat weight will be placed on too small of an area on the boat. This could damage the boat if you use Boat Trailer Deluxe Roller Bunks, # DL21741. Instead, quality carpeted bunks and some keel rollers like # 812 that are properly positioned for the shape of a tri-hull boat should work well. It is not that you cannot use roller bunks, you would have to make sure the weight is evenly distributed with additional rollers, like keel r

• Can Roller Bunks be Used on a Boat Trailer for a Hurricane SS211 Boat
  
• According to the research I did, I found that a Hurricane SS211 weighs in at about 2,990 pounds. That is not counting any gear that would be on the boat, water, fuel, and other items. All of these incidentals would push it over 3,000 pounds which would exceed the capacity of the Boat Trailer Deluxe Roller Bunks, # DL21741.

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.
