Union's StrongBOLT 3 Lever Mortice Deadlocks have plastic splinter guards for easy installation and a professional finish. In addition, the radius inner forend aids ease of installation. They can be installed in the many UK mortices without the need for additional carpentry or spoiling the edge of the door.

The chamfered bolt design increases the performance of the lock under side load testing and also makes drilling attack more difficult. Anti-pick and keyhole protection prevents forced entry by picking, and the hardened steel pins provide resistance to attack from sawing.

The deadbolt can be locked or unlocked by the key from either side. This deadbolt measures 14mm for secure positive deadlocking and additional resistance against attack.

2103S can be keyed alike with 2203S.

Forend finish: Polished brass.
Case size: 68mm x 89mm.
Backset: 45mm. This is the measurement from the edge of the door to the centre of the keyhole.
