Schlage L9070J LATA 622 Grade 1 Classroom Lock is engineered to meet the highest standards of durability and security. This Grade 1 classroom mortise lock features a Schlage FSIC Less Core and is designed with a sleek Latitude lever and an A Rose in a sophisticated flat black coated finish, ensuring both functionality and style. Ideal for high-traffic environments like schools, hospitals, and factories, this extra heavy-duty lock is constructed from heavy-gauge steel, providing excellent resistance to door edge attacks. Its all-metal, zinc dichromate-plated working parts enhance longevity, while the two-piece anti-friction tongue minimizes wear over time. Security is paramount, as demonstrated by its built-in features such as a break-away spindle that prevents unsecured failures and a hub blocking plate to deter manipulation. The spring-loaded fusible link ensures fail-secure operation in the event of a fire. Adaptability is a key feature of the L9070J, with a universal lock case that supports ten functions, field-reversible handing, and easy trim retrofits. The locking thumb-turn clearly indicates when the door is locked or unlocked, and its independent lever rotation enhances ease of use. With a 3-hour fire rating and UL listing, the Schlage L9070J is the perfect choice for demanding applications where reliability and safety are essential.
