The patented SST-II Hydraulic Bi-Folding System (Patent No. 8,714,229) opens vertically, allowing smooth, quiet access between environments with just the press of a button. By incorporating the SST-II Bi-Folding Door or Window System, the barrier between interior and exterior vanishes, letting the ambience of the outdoors flow in. Design the SST-II into your interior spaces and watch walls disappear, allowing light and motion to easily move throughout.
Shipped powder-coat finished. A full array of standard, non-standard, and custom colors are available, with few exceptions.
Manual lowering system in case of power failure
Total security without the use of locking mechanisms – The hydraulic cylinders draw the system panels closed with 1,000+ lbs. of force, creating a tight seal around the perimeter
Full perimeter weather seals
Integral mounting frame to limit loads on the structure
Heavy-duty bottom rollers are completely captured by the SST-II frame, keeping the system secure at all times
No floor track is required – Nothing to impair movement through the opening
When open the system forms an awning providing protection from the weather and sun
The use of hydraulics eliminates the need for limit switches
