Got these from Amazon. I saw a guide at Grand Isle that had them. He said they were great if you launch a lot.
Took me an hour to install them.
I had trailer welding work done and my old carpet was junk, so I got the next best thing.
Manufacturer is Tie Down Engineering.

Here is what she looked like while waiting on the trailer repair.
My boat blocking skills suck, but it didn't fall for almost a week on them blocks.

Shoulda put the talon down to make sure it didn't move

Not one time did my phone ring so I could at least go watch you work. Looks good and I would practice the boat blocking skills.

Gerald. I got them off of Amazon.com, which has the pricing.
They are built by Tiedown Engineering.
They are plastic, not teflon. Not as slippery as teflon, but more slippery then carpet.
I had broke brackets below the bunk boards. Got some welding done and took the carpet off and set these on the 2 X 6's and there are screws that come with them to screw them to the boards.
The boards were in good shape. Didn't change them out. The plastic is in sections. They come with self tapping stainless screws.
I found that predrilling the plastic makes the job go a lot faster and easier.

Thanks for sharing.
