HELP! Lower track got tossed

Hi there! Your roller looks like an older version of our 23-041, which just so happens to be compatible with our 23-242 track. I feel confident that this will work for you but you should note that it's 72" long, not 71". If you don't have room for that extra inch you will need to trim it off with a hacksaw.

As long as your rollers are in good condition then you can absolutely reuse them. If not, see the 23-041 bottom roller that I already mentioned as well as the 23-222C top roller.
