Safety Padlock Set for Lockout Use

This pack contains six Master Lock safety padlocks keyed alike so one key opens every unit. The thermoplastic bodies resist chemicals and carry a Danger header for clear identification. They suit maintenance teams needing consistent key access across multiple isolation points. Each lock includes two keys and labels for on-site marking.

Keyed-Alike Convenience with Labels

Supplying two keys per padlock means spares are immediately available without extra ordering. The included labels let technicians tag each lock with equipment details or authorisation data. This reduces downtime during shift changes because no key management system is required. The non-removable key design prevents accidental key loss while the shackle is open.

Hardened Steel Shackle and Thermoplastic Body

A 1/4 in hardened steel shackle provides cut resistance while the 3 in high thermoplastic body withstands corrosive environments. Vertical and horizontal shackle clearances of 1 1/2 in and 13/16 in respectively fit standard lockout hasps and valve covers. The open shackle type allows quick attachment without threading. Buyers needing a different key code per lock or a stainless shackle for extreme marine exposure should consider other options.

Questions about this item

Will the hardened-steel shackle need replacement after repeated lockout cycles?

The 1/4 in. hardened steel shackle resists cutting and corrosion, so it does not require scheduled replacement under normal lockout use.

What stops the shackle from opening if the key cylinder wears?

The non-removable key design keeps the key captive when unlocked, preventing cylinder wear from allowing unauthorised shackle release.

Does the thermoplastic body get too hot to handle in a boiler-room environment?

The chemical-resistant thermoplastic body insulates against conducted heat, remaining safe to touch during all-day exposure in industrial settings.
