The SST-II Hydraulic Bi-Fold System

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.

  • Dimensions: Custom

  • 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
