Exit Devices

January 4, 2002
The exit devices from Rutherford Controls International are nearly impossible to pry or force open. They use a patented, interlocking latch and strike design. Stainless steel jaws actually grip the strike, securing the door to the jamb and completely encasing the lock. Options available include models for three- and four-foot wide doors, lever or pull trim for exterior access, and a built-in alarm unit to create a simple traffic control or loss prevention system that's easy to install.
