The Union StrongBOLT 5 lever deadlock features a red powder coated steel case and is suitable for timber doors up to 54mm thick. It has a 20mm throw zinc deadbolt with steel rollers and has a chamfered design. This increases performance of the lock under side load testing and increases its resistance to drilling attacks. For additional security, the key hole has anti-pick protection and the hardened steel pins provide resistance to attack from sawing.
