The innovative high security dual tumbler (HSDT) lock is the most secure lock in our range thanks to its patented locking system. With more than 380 million combinations, this lock has a significantly higher picking and higher torque resistance due to the patented number and alignment of tumblers in the cylinder.

Lock Description

Certified to BS EN 1303:2015, the HSDT lock meets the standards which specify performance and other requirements for the strength, security, durability and corrosion resistance of the lock cylinders and their keys. For details see table below.

The lock is operated by use of an exclusive, secure, high quality key system made from steel. For additional security, each lock is paired with a security tag to order replacement keys. The key can also be customised with the addition of a sticker or overmoulded head shape.

Designed and manufactured in our European facilities, the HSDT lock provides our highest level of security for your asset management applications including ‘pay-at-pump’ and electric car charging stations, ATM’s and cash management, shop and museum displays.
