Inspection flaps
INSTRUCTION OF INSPECTION FLAP:
Inspection flaps of the "N" type - with a lock that prevents opening.
This flap type can be assembled both in the ceiling (and thus gaining access to lighting wires, tubes or to a hiding place at roof's peak) or in the wall, where gas meter, watt-hour meter or phone central, etc. may be hidden.
Flap consists of a galvanized double-side steel sheet (1.5 mm thick), which is subsequently painted with a gray ground lacquer, with fitted bistable locks of two-sided use that prevents the flap from self-acting opening. Furthermore, flaps with dimensions that exceed 500x500 mm have additionally installed chains that prevent the flap from full opening in case of accidental lock release.
