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.

Questions about this item

How much heat does the thermoplastic body of the 410 padlock absorb when left in direct sun all day?

The orange thermoplastic body resists chemicals and does not conduct heat like metal, so it stays cooler to the touch during extended outdoor exposure.

What key do I need to open this lock if I already own other Master Lock 410 keyed-alike units?

The lock uses a standard keyed-alike cylinder, so the same key that opens your existing 410 series padlocks will operate this one.

Will the 1/4 in metal shackle fit through the 13/16 in hasp holes on my older lockout stations?

Yes, the 1/4 in shackle diameter clears the 13/16 in horizontal and vertical clearance, so it fits existing hasps and lockout points.
