Master Lock Safety Padlock Keyed Alike Black 3/16 in PK3

Safety lockout padlock set

This three-pack of Master Lock safety padlocks is keyed alike so a single key operates every lock in the set. The thermoplastic body resists corrosion while the stainless-steel shackle provides strength for lockout-tagout procedures. Each padlock includes a non-removable key and a "Danger" header label for clear identification. The set suits maintenance teams, facility managers and industrial workers who need consistent keying across multiple isolation points.

Thermoplastic body with stainless shackle

A 1 7/8 in high thermoplastic body weighs less than metal alternatives and withstands harsh environments without rusting. The 3/16 in diameter stainless-steel shackle offers 5/8 in horizontal and 1 1/2 in vertical clearance to fit standard hasps and lockout devices. An 11/16 in body thickness adds durability while the open shackle design allows quick application and removal during shift changes or emergency procedures.

Two keys and labels included

Every pack supplies two standard keys that work all three padlocks, reducing the number of keys personnel must carry. The included "Danger" header labels attach to each lock body for immediate visual warning at energy isolation points. Non-removable keyways prevent keys from being left in unlocked padlocks, reinforcing lockout discipline. Buyers who need unique key codes per lock or a larger shackle diameter for oversized hasps should choose a different configuration.
