The 3571 Series Mortice Deadlocks are built for heavy-duty commercial and industrial applications, including institutions, clubs, schools, hospitals, hotels, and similar environments. Constructed from high-quality materials, these locks provide durability, strength, and reliability.

Various deadlocking functions are available, generally operated by a key from outside and a turnknob or key inside. Locks are deadlocked when the door is closed. For all deadlock functions, specify the primary lock (3571SC), which can then be adapted to suit the required function.
