What sizes are typical for oval profile mortice locks on timber doors?

Common case depths are 2.5" (64mm) and 3" (76mm). 3" is often used where a deeper backset is required, such as some fire door casings.

Do oval profile mortice locks include the cylinder?

No. Choose a matching oval cylinder separately to suit the door thickness, function and keying preference (keyed alike or master keyed).

Should I choose a sash lock or a deadlock?

Use a sash lock when you want handle-operated latching with a key-thrown deadbolt; use a deadlock where a latch is not required and a key-only deadbolt is preferred.

Are oval profile locks still recommended for new projects?

For new installations, many specifiers prefer Euro profile cases due to broader cylinder choice and long-term availability. Oval profile remains ideal for matching existing oval hardware.

Are 3-lever or 5-lever oval profile sash locks available?

No. Lever counts refer to traditional mortice key locks. Oval profile uses a separate cylinder rather than internal lever stacks.

Oval Profile Mortice Locks for Timber Doors – Sash & Deadlock Options

Oval profile locks are mortice lockcases designed for oval cylinders—ideal where a building already uses legacy oval hardware or master key suites. Choose between oval profile sash locks (latch + deadbolt) and oval profile deadlocks (deadbolt only). Available for delivery to London, Manchester, Birmingham, Leeds and across the UK.

What is an Oval Profile Lock?

A mortice lock fitted into a timber door that accepts an oval-shaped cylinder (not Euro). Cylinders can be swapped for keyed-alike or master keying without changing the whole case—useful for commercial and heritage properties.

Pros & Cons at a Glance

Pros: Best match for existing oval suites; flexible cylinder keying; neat with compatible furniture such as lock door handles on backplates (sash) or oval profile escutcheons (deadlocks).
Cons: Many manufacturers are moving to the Euro profile system; for new projects we recommend Euro for wider choice in the long term.

Detailed Guide to Oval Profile Locks

Sash vs Deadlock, Case Sizes & Legacy Compatibility

Oval profile mortice locks are chosen for timber doors where an existing suite uses oval cylinders. Pick Oval Profile Sash Locks when you need a handle-operated latch plus a key-thrown deadbolt; choose Oval Profile Deadlocks for clean, key-only security. Typical case sizes are 2.5" (64mm) and 3" (76mm) — the deeper case is common on thicker or fire-rated casings.

For a tidy installation, pair sash locks with Lock Door Handles on Backplates and finish deadlocks with Oval Profile Escutcheons. When replacing an existing lock, confirm the backset, follower size, forend style, and spindle compatibility, then select the correct Oval Profile Cylinder length and function to suit your door thickness and security requirements.
