Excellent services and pace of delivery. The Pack was a direct replacement for our bifold doors, which have seen heavy service since 2012. Only the lower runner needed to be replaced, as the roller housing had sheared in two, but obviously, they come in a pair. The top unit is in the drawer ‘just in case’. Great product, and I was able to make the change myself with some careful support of the door to give the right fitting height. If you have this make/type of bifold and an issue with top or bottom runner/roller then this is an ideal replacement.
