Standard Magnetic Door Retainers The most widely used door retaining device, these units are either floor or wall mounted and are wired into the fire alarm so they release upon a fire alarm activation.

These units offer the advantage of allowing the door to be left open at any angle, so they are perfect for care home room doors.
