Guidance & Use Cases

Sashlock vs Deadlock, Internal vs External, Practical Sizing

A mortice deadlock provides a key-operated deadbolt for secure locking, making it ideal for doors where you need extra security but no latch. Browse our range of Standard Mortice Key Deadlocks to find options in 2, 3, or 5 lever configurations, including BS 3621 certified locks for insurance compliance. Perfect for front doors, back doors, and other entry points where maximum strength is required.

A mortice sashlock combines a latch and deadbolt for everyday convenience with lever handles. Our Standard Mortice Key Sash Locks are available in 2 Lever Sash Locks, 3 Lever Sash Locks, and 5 Lever Sash Locks. For external doors, choose 5 lever British Standard mortice locks (BS 3621); for internal rooms, 2 lever or 3 lever may be suitable. Always check lock case dimensions, backset, and furniture type—knob sets often need a larger backset to avoid pinched fingers.
