Thunderbolt Heritage

Created for security and fashion, the Thunderbolt Heritage lock is a Key Turn Activated locking system which houses the cylinder at a heritage eye-level position, perfect for modern or traditional doors with ornate or architectural long bar or traditional pull door hardware.

Similar to the Thunderbolt™ locking system, the Thunderbolt Heritage features twin deadbolts in the upper and lower positions and 5 deadbolts as standard.

The Thunderbolt Heritage locking system is extremely easy to install and can provide any timber or composite door the perfect contemporary style look.
