This product is the easiest and cheapest method I have found to make loading your boat back on the trailer simpler and faster. The boat slides back on the carpeted bunks so much easier. Eliminates the need to consider more costly alterations to your boat trailer. This is the second boat trailer I have installed this product on and if I ever buy another boat this will be the first thing I put on the trailer. Be careful when puting your boat in the water because the boat slides off the trailer much easier too.
