That's the one, it's not the cheapest but it is really heavy duty material and should last a long time used on PT wood. The original bunks weren't even PT and they were completely rotten after 6 years. I glued mine on with outdoor carpet adhesive and used Stainless staples in the bottom side so hopefully I'm good for a few years.
I considered the UHMW plastic slides on the bunks but I normally back down the ramp with everything unhooked and was worried about the boat sliding off...
