3570 Series Mortice Nightlatch, Coverplates, Turn Adaptors & Hardware Parts

The 3570 Series Mortice Nightlatch is engineered for heavy-duty commercial and industrial applications, including institutions, clubs, schools, hospitals, hotels, and similar buildings. Constructed from high-quality materials, these locks deliver durability, strength, and reliability.

Various nightlatch functions are available, generally operated by a key from outside and a turnknob or key inside. The nightlatch locks automatically when the door is closed. For all nightlatch functions, specify the primary lock (3570SC), which can then be adapted to suit the required function.
