Our fully Gasketed Access Doors are commonly placed in laboratories, operating rooms, and other clean rooms and are easily installed in finished walls and ceilings of any construction. Doors and frames are fabricated from 18 gage, galvannealed steel with a concealed pivoting rod hinge that prevents distortion and closes door squarely. The 1” (25) wide frame is one piece construction and conceals rough wall opening. Wall frame is factory predrilled with 1/4" mounting holes for faster installation. The installed latch is screwdriver operated. They are delivered primed and ready for paint.
