All major components are extruded from high grade 6063 recyclable aluminum alloy. The system has been engineered from the inside out incorporating compact, heavy duty hardware requiring only a soft touch to operate quietly and smoothly. The standard finish is clear satin anodized; custom anodized colors are available per special order. The system accepts any 1/4" or 1/2" (including 1/2" laminated glass) thick panel material allowing for virtually unlimited design choices. All panels are cushioned by our proprietary clear silicone gasket and held securely in place by snap-in stops, enabling complete installation before glazing, as well as simplifying any repair or replacement.
