Duro locks are built with a revolutionary 12-pin cylinder system designed for complete locking protection.
Our highly secure mechanism uses two rows of six anti-drilling pins of varying length and double-grooves, making it almost impossible to pick.
Additionally, our patented 12-pin cylinder system offers a multitude of key combinations, and it is designed to be used with a large number of locks, such as profile cylinders, deadbolt cylinders, cam locks, and padlocks.
