"It was very advantageous to get a door system that was
floor supported."

Performs the same as Top-Hung Systems

Floor supported systems offer the same weather protection, performance, and testing as expected from our top-hung systems

smoother Operation

Floor supported systems are durable and offer much smoother operation with stainless steel wheels on a stainless steel track

to deal with building movement

Floor supported systems offer easier height adjustability should building movement occur - be it from heavy snow loads or building settling over time


"All seasons, it just works."

-Chris Chan-Piu, Director of Sales

retrofits made easy

Floor supported systems are ideal for applications where load-bearing capability of the header is a concern. The system's main weight is carried by the floor track.  The upper track is merely a guide.
