Our Electrified Rim Exit Device is manufactured on an Adams Rite bar. We have our own patented, less expensive (but very durable) method of electrifying these bars. Normally used on single storefront aluminum doors, we have a model for steel and wood doors as well. If you want to do a pair of doors, you can order our optional quick release mullion. No extra or proprietary power supply needed. Our units all draw less than one amp, are AC or DC compatible and are the least expensive electric panic exit device on the market. Outside key bypass is easy to install (cylinder not included) and can be equipped with any variety of rim cylinders.
