1 OVERVIEW AND DOOR PREPARATION

33/3550AWDC

Instead of traditional rods, concealed vertical cables are utilized, making use of a proven technology
that enables quick installation and allows for easy maintenance. Simplified sizing, ease of adjustment
and greater door integrity make the Wood Door Concealed exit device a more secure solution, without
the complexity associated with traditional concealed systems. Another key benefit of the system is the
ability to make adjustments to the system by simply removing the scalp plate from the edge of the
door.
