DynaLock 2800 Series Electromagnetic Door Holders are designed to hold self-closing fire or smoke barrier doors open until automatically released by fire alarm, smoke detection, or sprinkler systems.

They can also be manually controlled wherever instant closing of doors is required for safety or convenience.

Each door holder assembly consists of a floor or wall mounted heavy-duty electromagnet, a self adjusting and pivoting armature, and all necessary mounting hardware. All models are field selectable to operate on 24VAC, 24VDC, or 120VAC input voltage. Convenient screw terminals are provided for field hook-up. All holder models are UL listed.

Two optional telescoping Extension Rods are available, to extend the armature up to 12", for installations where a wide standoff distance between the electromagnet and armature mounting locations exist.

DynaLock 2800 Door Holders each provide 25 lbs. of holding force, allowing manual door closure when electromagnets are energized.
