Union Strongbolt 3 Lever Mortice Deadlock

This Union StrongBOLT 3 Lever Mortice Deadlock features a polished brass forend finish with an 81mm case size and 57mm backset, making it suitable for thicker doors or applications requiring a deeper backset measurement. The polished brass finish delivers an attractive traditional appearance that complements period door furniture and classic interiors. The lock incorporates plastic splinter guards for easy installation and a professional finish, with a radius inner forend that aids fitting into many UK mortices without requiring additional carpentry or spoiling the door edge. The chamfered 14mm deadbolt design increases performance under side load testing and provides enhanced resistance against drilling attacks, whilst anti-pick and keyhole protection with hardened steel pins prevents forced entry attempts. The deadbolt can be locked or unlocked by key from either side, and this model can be keyed alike with the 2203S for convenient multi-door installations.
