A replacement top guide to repair existing bifold installations, featuring a 160 x 60mm support bar
This top guide assembly is used above the roller at the top of bi-fold door installations wherever two hinged door leaves sit in the running track. It works with the bifold roller to support moving door panels at the top to ensure that the door stays in the track. This top guide can also be used as a bottom roller by inverting and adding rollers from the bottom rollers that you are replacing.
