Why Choose a Commercial Mortise Lock? Mortise locks are the gold standard for institutional security. Unlike cylindrical locks that fit through a bored hole, a mortise lock requires a rectangular pocket—or "mortise"—machined into the door edge. This design allows for a heavy-gauge steel case and more complex internal mechanisms, resulting in a lock that can withstand over 1 million cycles. Whether you need Classroom Security for a school or Fail-Safe electrified hardware for an office, our selection of UL Fire-Rated mortise locks meets all major building codes.
