G2000® High Performance & Security Lock

"This high performance lock range offers superb security and high performance for external entrance doorsets"

Ideal for the housing provider or facilities manager needing to improve security and traceability for existing doors. The G2000® lock offers truly innovative design with a proven track record of burglary prevention.  High quality components guarantee many years of fault-free operation.  With an integral cylinder within the lock, it is designed to withstand drilling, hacksawing and extraction.

The G2000®  is extensively tested, including the General Vulnerability Testing (anti-bump testing) within the range of British standards.  It is not possible to snap the cylinder as it is an integral part of the lock design.

To  prevent the breach of a doorset through the letterbox by the thumbturn being flipped or tampered with, there is the innovative push and turn function.  This is also useful to prevent young children from inadvertently exiting the door without supervision.

The G2000 range employs a key registered system.  Not only are the keys linked to  a strict key registration procedure, the shape of the key is design-registered and trademarked against unauthorised copying.
