Abstract

A dampener for an exit device may be disposed between a portion of an exit device actuator and an exit device chassis so that the dampener dampens vibrations to reduce noise of the exit device and/or inhibit unintentional movement of the actuator to an actuated position. The dampener may be composed at least partially of a viscoelastic material.
