Discover our Sash Locks range, featuring the trusted ERA Fortress 5-Lever Mortice Sashlock in both satin chrome and brass. Delivered with a built-in latch and deadbolt, these locks bring together convenience, compliance, and solid security for both internal and external doors.
Why the ERA Fortress 5-Lever Sashlock Stands Out
Dual-Function Locking Mechanism Combines a spring-loaded latch for everyday access with a 5-lever deadbolt for strong, key-operated security—perfect for balancing ease of use and protection.
British Standard BS 3621 Rating Designed to meet insurance and security standards, the 5-lever configuration ensures this lock is suitable for exterior doors needing extra protection.
Ideal Fit for Lever-Handle Doors Mortice-style locking requires complementary lever-on-rose handles. Ensure your handles operate the latch independently of the deadbolt for efficient use.
Versatile Application Perfect for both internal and external entrances—use in hallways, bedrooms, or front/back doors where you seek convenience along with security.
Who Should Choose This Collection?
Homeowners needing a lock that delivers both daily convenience and reliable, insurance-approved security.
Those upgrading from basic 3-lever mechanisms to higher-security 5-lever options.
Anyone with lever-handled doors in need of a dependable lock that works seamlessly and meets compliance standards.
A sashlock combines a handle-operated latch with a key-operated 5-lever deadbolt in one case — the standard lock for timber front and back doors with lever handles. Lock the deadbolt at night and use the latch all day.
The ERA Fortress 5-lever sashlock is designed to the British Standard insurance benchmark — check the faceplate Kitemark on your chosen variant. BS3621 is what most insurers' policy wording requires on external timber doors.
Lever-on-backplate handles with a keyhole cutout matching the lock's centres, or lever-on-rose handles with a separate escutcheon. The handles drive the latch; the key works the deadbolt independently.
If the door has handles and you want one case doing both jobs, a sashlock. If the door already has a nightlatch handling day-to-day closing, add a deadlock below it. Same 5-lever security either way.
