LPU Ranking – Green Belt – 401 Keyway
The 410 LOTO is a 6-pin core containing 5 spools and 1 lightly serrated pin, in random positions. The keyway is physically restricted by the plastic body to rotate only clockwise, but the core is able to rotate counter-clockwise using a tension wrench underneath the body. The lock can be permanently damaged by rotating the core 180° clockwise, as this can drop the key pins out of the lock or into the lock body.
