Lockout padlock for group safety

This Master Lock safety padlock uses a blue thermoplastic body with a hardened steel shackle and a non-removable key. The keyed-alike set means every lock in the pack opens with the same two keys, simplifying key management for maintenance teams. A "Danger" header and included labels support clear hazard identification during lockout procedures. Chemical resistance helps the lock withstand industrial environments.

Teams sharing one key code

The pack suits facilities where multiple workers must secure the same energy-isolation points with identical keys. Buyers who need each lock to have a unique key code should choose a keyed-different option instead. Users who prefer a metal lock body or a different shackle diameter will need another model. The fixed keyway cannot be re-keyed on site.

Fits standard lockout hasps

The 1/4 in shackle diameter and 1 1/2 in vertical clearance accept common lockout hasps and valve covers. Two supplied keys and adhesive labels let crews tag and secure equipment immediately. The non-removable key prevents accidental key loss while the lock is open. Thermoplastic construction reduces weight on portable lockout stations.

Questions about this item

Does this padlock require a specific hasp or chain link size to fit the 1/4 in shackle?

The shackle diameter is 1/4 in with a horizontal clearance of 13/16 in and vertical clearance of 1 1/2 in, so the attachment point must accommodate those dimensions.

Can I use these keyed-alike padlocks alongside existing Master Lock padlocks that use a different key code?

These three padlocks share the same key code and include two keys; they will not open locks with a different key code unless those locks are also keyed alike to this set.

How do I confirm the non-removable key feature is working after I lock the shackle?

After locking, the key cannot be withdrawn while the shackle is open; it only releases once the shackle is snapped shut, confirming the safety function is active.
