The OMR 160500 is a T6 triangular-drive lock with a pressure-activated quarter-turn mechanism. The die-cast zinc body houses a spring-loaded rotor that requires key pressure before rotation, preventing accidental opening due to vibration.

A key feature of this model is the 74 mm steel extension fixed to the rotor, allowing the cam position to be adjusted from 34.70 mm to 81.70 mm without using bent cams. The T6 female drive is compatible with box cylinders featuring an 8 mm triangular male key.

The lock is suitable for applications requiring extended reach beyond deep frames or boxed structures, such as railway and naval equipment, industrial vehicles, forklifts, metal carpentry, road signage panels, advertising structures and technical enclosures.
