ALPRO Screw-In Mortice Deadlatch Case

The Alpro Screw-In Mortice Deadlatch Case is a highly reliable, narrow-style latch body designed primarily for commercial aluminium doors where automatic locking upon closure is required. This round mortice cylinder deadlatch offers flexible security control and is fully compatible with Alpro's range of electric strikes to provide remote access control functionality.

The deadlatch can also be operated using exit trim, such as the Alpro 459 paddle handle (requires a cam plug). When the door is closed, the deadlatching mechanism prevents the latch bolt from being forced back or tampered with, ensuring robust security.

This product is supplied as a case only (without a faceplate, cylinder, or handles). It accepts standard 1 5/32" screw-in key or thumbturn cylinders and fits industry-standard ANSI cut-outs.

Please note that this deadlatch is available in multiple configurations. You can choose from 25mm or 28mm backsets, and left-hand or right-hand operations. Please select your required backset, handing, and case depth from the options below.
