Fire doors and glass doors cannot be pierced. It is thus impossible to fasten the electro-magnet's strike plate directly on the door. This accessory is designed to overcome the inconvenience. It can be fastened with screw or glue.
This accessory is designed for the assembly of the electro-magnets over the door, on the jamb and not on the header. There are three anodised aluminium parts: an `L` to fasten the electro-magnet, and the two parts of an adjustable `Z`, which receives the strike plate.
