Quarter Turn Cam Lock with 8mm Triangular Insert GH=40mm

The Factory Yard Quarter Turn Cam Lock with an 8mm triangular insert is a secure and reliable locking solution for industrial enclosures, electrical cabinets and utility infrastructure. Designed with a GH (grip height/thread length) of 40mm, it is suitable for thicker door panels and insulated enclosure doors where standard cam locks may not provide sufficient engagement.

Manufactured from high-quality zinc die casting with a bright chrome plated finish, this lock combines durability, corrosion resistance and an attractive appearance. The straight cam provides dependable latching performance and can be supplied with alternative cam lengths and offsets to suit different enclosure designs.

The 8mm triangular insert is one of the most widely used utility locking standards, commonly found on electrical distribution cabinets, telecom enclosures, water treatment equipment, gas installations and public infrastructure.
