Mul-T-Lock Interactive® Platform - High Security with Patented Key Control
Mul-T-Lock®’s High Security cylinders have a special telescopic pin tumbler mechanism with internal and external pins. Both the internal and the external shear lines must be aligned simultaneously in order for the plug to rotate..
The patented Mul-T-Lock plug has a special structure. When the top and bottom pins, plug and body meet, a three-dimensional shear line is formed, creating an almost perfect spherical shape. Steel inserts enhance anti-drilling resistance.
These features provide an added security dimension, amplifying the Mul-T-Lock cylinder’s pick-and-drill resistance for High Security needs. When master keyed, additional side pins or back pins can be incorporated.
