Master Lock 410 padlock keyed alike orange 1-1/2 in shackle

Lockout Padlock for Safety Procedures

This Master Lock 410 padlock is built for lockout and tagout programmes where a single key must open multiple units. The orange thermoplastic body resists chemicals and remains visible in industrial settings. A metal shackle provides the physical barrier, while the non-removable key design prevents the key from being left in the lock. It suits maintenance teams securing energy-isolation points.

Sustained Exposure in Industrial Areas

The thermoplastic body maintains its shape and colour when subjected to oils, solvents and cleaning agents over long shifts. Unlike painted metal, the colour runs through the material so it does not chip or fade with repeated handling. The shackle clearance stays consistent because the body does not swell or corrode. This stability keeps the lock functional throughout extended lockout periods.

Build Details and Daily Use

A 1/4 in diameter metal shackle with 1 1/2 in vertical clearance fits standard hasps and lockout devices. The 13/16 in horizontal clearance allows the shackle to pass through adjacent holes without binding. Keyed-alike cylinders mean one key operates every padlock in the set, reducing the number of keys a technician carries. The reserved safety cylinder is not user-serviceable, so the lock stays tamper-resistant.
