Why Flat Track Sliding Door Hardware

Flat Track is a top hung system, where the track is mounted above the opening. Door panels are outfitted with a pair of hangers that are assembled to specifically suite your door thickness. Only one pair of hangers is recommended per door. These hangers roll quietly on top of the flat track. The track is custom cut to length to suite each opening/application with mounting holes spaced equally or per the customer's designation. The track is offset from the wall/solid blocking using custom length wall spacers and fastened into place by either lag screws or another type of appropriate fastener. The weight of the door is supported only by the flat track system. A bottom guide/roller is used to stabilize the bottom of the door.
