Lockout padlock for group safety procedures

This Master Lock lockout padlock uses a blue thermoplastic body and a 3/16 in stainless steel shackle. The keyed-alike configuration means every padlock in the pack opens with the same two keys. It is intended for maintenance teams that need identical keys across multiple lockout points.

Included keys and labels support organised lockout

Each pack contains twelve padlocks, two keys and accompanying labels. The labels allow technicians to mark the responsible person or department on the lock body. Non-removable keyways prevent the key from being left in the shackle after locking, reducing accidental removal.

Simple installation with standard shackle clearance

The open shackle design fits through common hasp holes and lockout devices with 5/8 in horizontal and 1 1/2 in vertical clearance. Corrosion-resistant materials suit indoor and outdoor industrial environments. Ensure the shackle diameter matches the lockout point before deployment.

Questions about this item

Will the shackle or lock body need replacement after repeated lockout cycles?

The stainless steel shackle resists corrosion and the thermoplastic body withstands industrial use, so neither component typically requires scheduled replacement under normal lockout procedures.

What stops me from adding more padlocks to the same keyed-alike set later?

Each pack contains twelve padlocks sharing one key code; ordering additional packs will produce a different key code unless the supplier confirms the same key reference.

Does the non-removable key feature cause the lock to heat up or bind during all-day use?

The non-removable key simply prevents key loss while the padlock is open; it adds no friction or heat during continuous service.
