In-Depth Guide to 3 Lever Mortice Sash Locks
How They Work, Key Features & Benefits
A 3 lever mortice sash lock sits neatly inside a morticed cut-out in the door edge, combining a latch for everyday use with a deadbolt for locking. The three-lever mechanism means more key variations and stronger resistance to casual picking than a 2 lever model, making it ideal for rooms requiring more privacy and moderate security.
These locks are a popular choice for internal door security in bedrooms, home offices, and utility areas. Available in both 64mm and 76mm sizes, they are compatible with standard UK door furniture and are ideal for pairing with lock door handles on a backplate for a neat, professional finish.
