The patent-pending, hydraulically-operated 50/50 Door and Window System combines the best features from our SST-II Bi-Fold and Single-Swing Systems. The 50/50 provides an incredibly clean opening, requires minimal space in the open position and requires no maintenance, making it perfectly suited for architectural, commercial and residential designs.
With its ease of use operation, one office personnel can operate the opening and closing of the Crown 50/50 unit making ideal for an office and or restaurant location.
A massive benefit to the 50/50 system is that it requires no maintenance. There are no hinges or rollers and all pivot points utilize maintenance-free bearings.
The use of hydraulic cylinders eliminates counter-weights, cables, locking mechanisms, pulleys, springs, etc., providing a clean panel face, free from obstruction. This combined with it’s all steel construction allows for more glass volume and greater visibility.
With its cylinders positioned vertically, the mechanism becomes hidden entirely within the jamb housing giving a clear opening from one space to the next.
