The FF Systems F2DF access panel consists of a welded aluminum frame and is available with 1/2" (12.7 mm) or 5/8" (15.9 mm) inlayed drywall and two latches.
Both an outer and an inner frame assembly consists of high grade aluminum which is bonded with a special welding process. For sizes 12” x 12” (305 mm x 305 mm) and up the access panels are equipped with a safety-system to prevent accidental opening. This safety system must be reattached if the hatch is removed.
The reveal of 1/16 of an inch (1.59 mm) is visible between the outer frame and door hatch. The concealed snap locks open the access panel when pressure is applied to the spring loaded latch side.
