Mul-T-Lock Cylinder Platforms

These high security cylinders have a unique telescopic pin tumbler mechanism using external and internal pins. The external and internal shear lines have to be aligned so the plug can rotate. When the top and bottom pins, plug and body meet, a three-dimensional shear line is formed to create a spherical shape.

Steel inserts ensure anti-drilling resistance.
If the cylinder is Master keyed, additional side and or back pins can be added.
