The KPD/KPDU smoke exhaust dampers and the KP-1, KP-2 wall-mounted fire-resisting dampers (1 flange) can be additionally equipped with a protective grille.
The protective grille serves for protection against unauthorized access to the damper and its actuating mechanism.
The grille is only made from galvanized steel.
The grille is attached directly to the damper flange by means of self-tapping screws.
