Mortise Locks: Robust Solutions for Secure Doors

Mortise locks are fitted into a pocket cut into the door and are known for their strength and longevity. Commonly used on external doors and high-use internal doors, they provide a high degree of security and are compatible with a variety of handle and cylinder combinations.

What to consider when choosing a mortise lock

Check the lock case size, backset and the type of cylinder required. Decide whether you need a deadlatch, sashlock or multipoint variant and whether fire certification or insurance compliance is required. Keep the door thickness and strike plate reinforcement in mind.

Typical benefits and options

• High security and durability for external entrances.
• Compatible with euro or profile cylinders for key control.
• Various backsets and case depths to suit different doors.
• Options for sashlocks with integrated latch and deadbolt action.
• Fire-rated models available for safety-critical doors.

Mortise locks require precise installation and often professional fitting. Look for quality finishes and consider reinforced strike plates to improve resistance to forced entry. Clearance or refurbished lock cases may be available for non-critical applications, but always verify condition and certification for security-sensitive doors.
