Our DRX range of door retainers is ideally suited to applications where maximum protection is needed against vandalism or accidental damage. It features a rugged cast aluminium housing, a holding magnet with integral ejection pin and a manual release switch.

Installation is, with knockouts provided for entry of surface mount conduit, there is ample sound to connect external wiring to the 4.0mm terminals.

Each DRX door retainer is fitted with a spring loaded release pin mounted centrally within the electro-magnet. On power off, the release pin then ensures that the fire door is pushed away from the electro-magnet.

All door holders are supplied complete with a door mounting keeper plate. Additional accessory products are available, including floor brackets, chains and additional keeper plates.
