Product Description

Electromagnetic Door Holders and Releases
 

What is electromagnetic door stopper?

Electromagnetic door holders and releasers keep doors open until they are released by fire-alarm systems, 

remote smoke detectors, or other switching devices. They provide a high holding force. In the event of a power 

failure, they release the door to a closed position to keep the facility secure.

Removing the Old Magnetic Door Stop
