Pro-Tip from Our Locksmiths: The 9975 mortise lock exit device combines exit device push bar with a mortise lock body recessed into the door edge. This gives you the latching security of a mortise lock with code-compliant panic hardware. Popular on storefront doors where you need both security and life safety.
