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.

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.
