Yale 2150 Panic Rated Square Bolt Exit Device

Just as easy to open as traditional latchbolts, the SquareBolt exit device’s unique construction offers innovative protection. Its patented SquareBolt  (Pat. no. 5,605,362) design presents an improved physical barrier over standard rim latchbolts.  The SquareBolt exit device locks into place and stays there. Credit cards, crowbars, door rattling and shaking are resisted,  significantly reducing the threat of unauthorized entry.
