Types of Union Locks

Union produces a comprehensive range of locks to suit every door and application:

Mortice Sashlocks

The classic Union mortice sashlock combines a latch bolt (operated by a handle) with a deadbolt (operated by a key). It is the most common type of lock for exterior doors in the UK. Union sashlocks are available in 2-lever, 3-lever, and 5-lever versions, with 5-lever models meeting the rigorous BS3621 standard for thief-resistant locks . Many models are also available in fire-rated versions.

Mortice Deadlocks

A Union mortice deadlock provides a single deadbolt operated by a key, with no latch. It is often used in addition to a latch or as a secondary lock on exterior doors. Deadlocks offer excellent security and are available in various sizes and finishes.

Mortice Latches

A Union mortice latch provides a spring-loaded latch bolt operated by a handle, with no locking mechanism. It is ideal for interior passage doors, closets, and hallways where security is not required.

Multi-Point Locks

Union multi-point locks, such as the StrongBOLT range, provide multiple locking points along the door edge for superior security. These locks are ideal for exterior doors and are often used in conjunction with a cylinder for keyed access.

Padlocks

Union also produces a range of padlocks for gates, sheds, and storage units, including laminated steel and brass models .

Rim Locks

A Union rim lock is surface-mounted on the door face rather than mortised into the edge. It is a traditional choice for older properties and is easy to install.
