A sash lock, also known as a mortice sashlock, combines a latch and a deadbolt in one lock case. It is morticed into the door edge and typically operated by lever handles, with key locking for added security.

What is the difference between a sash lock and a deadlock?

A sash lock includes a latch and a deadbolt, while a deadlock focuses purely on locking security without a latch. Deadlocks are commonly chosen for higher security on external doors.

Are From The Anvil deadlocks suitable for external doors?

Yes. Deadlocks are widely used on external doors where security is a priority, often alongside a sash lock to create a more secure locking setup.

What size mortice sash lock do I need?

Common sizes include 2.5 inch and 3 inch mortice locks, with larger 5 inch and 6 inch options used for horizontal mortice sash locks. The correct size depends on door thickness, backset requirements and hardware style.

Do From The Anvil sash locks come in different finishes?

Yes. From The Anvil sash locks and deadlocks are available in a wide range of finishes, including aged, polished and satin options, to match period and contemporary door furniture.

Can I fit a deadlock above and below a sash lock?

Yes. Installing a deadlock above and below a central sash lock is a popular way to improve door security, especially on external doors.

Sash Lock vs Deadlock

A sash lock, also known as a mortice sashlock, combines both a latch and deadbolt into one robust mechanism. These are morticed into the edge of your door and operated by lever handles for smooth security. In contrast, a deadlock focuses solely on high-security locking and is activated by a key without a latch feature.

Extra Protection for External Doors

For those wanting maximum protection, many opt for a three-point solution by installing a deadlock above and below the central sash lock. This strategic locking approach provides enhanced peace of mind for external doors.

Horizontal Mortice Sash Locks for Period Properties

We also supply horizontal mortice sash locks, which are ideal for period properties and traditional interiors using mortice knobs. These classic configurations place the keyhole beside the handle rather than below it. Please note that these versions are not insurance rated, so we recommend adding a certified 5-lever deadlock beneath for additional security.
