Lockout Padlock for Energy Isolation

This Master Lock padlock is built for lockout-tagout procedures where multiple locks must share a single key. The thermoplastic body resists chemicals and the steel shackle provides cut resistance. It suits maintenance teams, facility managers and authorised personnel who need consistent keyed-alike access across several lock points.

Check Key System and Shackle Fit

Verify that your existing lockout stations use a keyed-alike system compatible with the standard key style supplied. Confirm the 1/4 inch shackle diameter fits the hasp, valve or breaker openings you intend to secure. Ensure the 13/16 inch horizontal and 1 1/2 inch vertical clearances match the hardware spacing on your equipment.

Thermoplastic Body with Non-Removable Key

The red thermoplastic body is lightweight, non-conductive and marked with a danger header for clear visual identification. A non-removable key prevents accidental key loss while the lock is open. Two keys and labelling labels are included for immediate deployment. The open shackle design allows quick attachment to standard lockout points.

Questions about this item

Does the padlock come with keys and labels, or do I need to order them separately?

The pack includes two keys and a label for identification, so nothing extra is required for basic lockout use.

Should I choose the keyed-alike version or a different keying option for a team?

Keyed alike means every lock in the set opens with the same key, simplifying key management for a single authorised person or small crew.

What does the 1/4-inch shackle diameter mean when the lock is on a real hasp?

A 1/4-inch steel shackle fits standard lockout hasps and provides strong cut resistance while still passing through typical 13/16-inch clearance holes.
