Get the Right Lock First Time
Expert Guidance You Can Trust
Choosing the correct mortice lock is essential for both security and compliance with UK insurance requirements. A 3 Lever Mortice Deadlock is best suited for internal doors or low-risk areas, providing basic security at a cost-effective price. For external front and back doors, a 5 Lever Mortice Deadlock tested to BS3621 is recommended, as it meets insurance and police approval standards.
If you prefer a lock that also operates the latch and can be used with a handle set, a 5 Lever Sash Lock may be the ideal choice, combining security with everyday convenience.
We can advise on case sizes (64mm or 76mm), finishes to match your décor, and compatible accessories such as Standard Profile Escutcheons and Door Furniture.
