The DRW door retainer is available in two casings, a flame retardent low profile ABS plastic body, specially designed for Cranford and a single gang metal-bodied version.

Each unit features a spring-loaded release pin mounted centrally within the electromagnet ensuring that on power off the fire door is pushed safely and effectively away from the keeper plate.

The 200N version is available as either a dc or ac unit and 500N version available as dc only.
