Material

Construction
Louver z-blade louver is riveted to the operating bar and frame at 1" intervals to welded 1-9/16" deep frame. Mechanical stop holds blades open. Frame mitered and welded corners screws fastened through prepared frame into louver core leaving corridor side of frame free of fasteners.
