ML9050 Heavy Duty Commercial Mortise Lock – Office/Entrance
The ML9050 is built for high-traffic, high-security applications, meeting the ANSI/BHMA A156.13 Series 1000 Grade 1 standard — the highest rating for strength and durability. Designed with a heavy gauge plated steel lock case and stainless steel latch, guard bolt, and armored front, it provides long-lasting performance and resistance to forced entry.
This Office/Entrance function allows the latch bolt to be operated by a lever from either side. The outside lever can be locked by key or by turning the inside button, and unlocked by key from the outside or by turning the inside lever, making it ideal for offices, storerooms, and secure rooms requiring quick interior egress.
