Union L2370 Nightlatch

The Union L2370 Mortice Nightlatch is a high-security locking solution designed for timber doors. Its primary function is to provide automatic deadlocking, ensuring that the door is securely locked as soon as it is shut. This makes it an ideal choice for both residential and commercial applications where constant security is a priority.

Operation is straightforward: the latchbolt is withdrawn by a profile cylinder from the outside and by a lever handle from the inside. For applications requiring key operation from both sides, it can be used with a double cylinder. The lockcase is specifically engineered to accommodate both Euro and Oval profile cylinders, offering versatility during installation.

Technical features include:

• Automatic Deadlocking: Increases security by ensuring the latch cannot be shimmed or forced when the door is closed.
• Reversible Latch: The latchbolt can be easily reversed without opening the lockcase, making it suitable for any door orientation.
• Furniture Compatibility: The case is pierced to accept bolt-through furniture, providing a more secure and stable handle mounting.
• Unsprung Handle Compatibility: Specifically designed for use with unsprung lever handles via its 8mm follower.

This nightlatch case is commonly used as a reliable replacement for existing mortice locks or as part of a new security installation on external timber doors.
