Electro-Magnetic Door Holders
Introduction
The MH Series Electromagnetic Fire Door Holders
are constructed of the finest materials available.
Each wall mount door holder is made of durable
die-cast metal and finished in a high lusterdouble
chrome plating for a high quality appearance.
For wall mount units, standard dual voltage AC
or DC inputs reduce stocking requirements with
12/24V and 24/120V models. The 24/120V
model draws a mere 15mA @ 24VAC or DC,
helping keep overall job costs to a minimum.
The basic units offer superiority reliability with
built-in transient protection and low residual
magnetism so they release easily even on new
ADA low pressure door closers.

- Dual Voltage Inputs
- Self-Adjusting Swivel Catch Plate Adjusts to Changes In Door Alignment
- Optional Extention Rod For Greater Jardware Clearance
- Low Residule Magnetism
- Built-In Transient Protection
- Available In Single & Double Floor Mounted Units
