About this product
This Union StrongBOLT 3 lever mortice deadlock has a stainless steel forend finish, offering good corrosion resistance and a modern appearance. The case measures 81mm x 89mm with a 57mm backset, suiting thicker doors. Plastic splinter guards and a radius inner forend allow fitting into many UK mortices without extra carpentry or spoiling the door edge. The 14mm chamfered deadbolt improves performance under side load and resists drilling attack, while anti-pick and keyhole protection with hardened steel pins guards against picking and sawing attempts. The deadbolt can be locked or unlocked by key from either side, and this model can be keyed alike with the 2203S for multi-door installations.
