🔳 JR Products 10121 Premium Vinyl Insert - White, 1 inch x 100 feet Review

When I tried this product, it immediately began to crack and peel. The material was thin and flimsy, and did not withstand any wear and tear.

Once you get to the track it will be very easy to work with, make sure the extensions on the outside go in the right direction, I did added an image. I've found that it's a lot easier to pinch and push into the splint than poke one side and then push the other side if you have another pair of hands, works well for pinching if the another person pushes them into the rail. The weight of the material is good and flexible.

There is a significant quality difference here. It's a lot thicker and better designed than other products I've used on my old camper last year. I will be replacing all the trim tires on my new RV. It's not that old trailer (2013 Keystone Sprinter - Premium 15th Anniversary) but the original rubber is already thin and cracked. This is a very good product and worth the extra cost.
