Crown Door

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.

Folding open, vertically, like its larger sibling, the Bi-Fold Electric System allows for the same smooth access between environments with just the press of a button.

The Single Swing Hydraulic System opens out fully, providing almost the entire rough opening height clear – Perfect for allowing large machinery into and out of a space or getting every inch of height possible out of a counter or bar top application.

The 50/50 provides an incredibly clean opening, requires minimal exterior space in the open position, maximizes clear opening height, and requires no maintenance, making it perfectly suited for architectural, commercial, and residential designs.

Available in custom sizes from counter-top application to two-story atriums, the Vertical Lift System provides an impressive visual statement supported by well-engineered operation.

Providing greater headroom and offering more overhead protection than the Bi-Fold System, the Single Swing System is well suited for everything from commercial food service to private residential pass-through.
