Dorgard Fire Door Retainers

The Dorgard is a reliable solution that allows you to hold your fire doors open at any angle for improved ventilation, access, and convenience. In the event of a fire, the device will automatically release enabling the fire door to close by responding to the sound of a fire alarm. When the alarm sounds at 65db or more (as per BS 5859-1) for 14 continuous seconds, the Dorgard will release allowing the fire door to close normally.
