Strongbolt 3 Lever Mortice Deadlock Stainless Steel 81mm 89mm

This Union StrongBOLT 3 Lever Mortice Deadlock features a stainless steel forend finish with an 81mm case size and 57mm backset, making it suitable for thicker doors or applications requiring a deeper backset measurement. The stainless steel finish offers superior corrosion resistance and a contemporary appearance, ideal for modern installations or high-moisture environments such as coastal properties. 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.
