Hey thanks for the information. I haven't been able to find anything that resembles the track online. The pool cover manufacturer (Cover Pools) may be able to help since they did the install. However, a previous owner had it done, and I'm guessing it's been 10-15 years since any work was completed there. (we replaced the cover in 2007)

The term "cantilever" was helpful... thanks for that. I just want to avoid draining the pool for now so even a temporary fix would suffice until we have the funds to replace the liner. I could build a ceramic tile overlay too.. it's just getting the vinyl bead firmly attached to the metal base that's troublesome...
