PISA style aluminum frame doors available in Natural (aluminum) or Black finish and a full range of available inserts. The dimensions of the frame outlined on the drawing. This type of frame is referred to as wide aluminum frame; therefore it requires a standard hinge with 35mm cup. PISA frames are noted for an extended side wall that covers the edge of the glass and no front lip. All doors are assembled with special steel corner brackets that need to be taken in consideration when locating a hinge hole as no drilling should be done within corner bracket areas; otherwise hinge holes can be pre-drilled in any required areas. All assembled doors come with concealed gasket that provide protection when the doors are slammed and also offer tighter assembly of the inserts.
