Frequently Asked Questions

What is a deadlock?
A deadlock is a mortice lock that operates using a key or thumbturn and does not include a spring latch. It provides a high level of security and is commonly fitted to entrance doors alongside other locking hardware.

What is the difference between a deadlock and a sashlock?
A deadlock contains only a locking bolt and is operated by a key or thumbturn. A sashlock combines a spring latch and a deadbolt in a single lock case, allowing the door to be opened using a lever handle while also providing a locking function.
