Norton Rixson 981M Tri-Volt Electromagnetic Door Holder/Release for Back-to-Back Doors, Floor Mount, Sprayed Aluminum

For reliable control of back-to-back fire doors, the Norton Rixson 981M Tri-Volt electromagnetic door holder delivers durable, professional performance. This floor-mount electromagnetic door holder is engineered for life-safety and security applications where consistent holding force and clean installation matter. The 981M supports tri-volt operation to simplify electrical compatibility on mixed-voltage job sites and minimize change orders. Its compact floor plate occupies just 6-5/8" (168 mm) of floor space and provides a 6.61" door clearance from the floor, making it ideal for narrow corridors and paired door installations.

Concealed wiring safeguards connections from tampering while the sprayed aluminum finish resists wear in commercial environments. Built for fire door applications, the 981M integrates easily with fire alarm, access control, and monitoring systems to ensure coordinated release during emergencies. Manufactured by Norton Rixson (ASSA ABLOY) in the U.S., this unit balances robust construction with a low visual profile for architectural sensitivity.
