Safety Lockout Padlock

The Master Lock lockout padlock is a key-retaining safety device built for industrial lockout-tagout procedures. Its thermoplastic body and stainless-steel shackle resist corrosion in harsh environments. The key cannot be removed while the shackle is open, ensuring the lock stays secured during maintenance. Bright yellow colour and included danger labels provide clear visual identification on job sites.

Durable Thermoplastic Construction

The non-conductive thermoplastic body withstands chemical exposure and extreme temperatures without degrading. Stainless-steel shackle resists rust and cutting attempts during normal use. Key-retaining mechanism prevents accidental unlocking when workers are inside hazardous zones. No power source or moving parts mean zero operational noise or energy draw.

Replaces Basic Padlocks

This unit upgrades from standard keyed-alike padlocks where individual accountability is required. Keyed-different cylinders ensure each authorised worker holds a unique key, preventing unauthorised removal. The jump is worth it when regulations demand personal lock control and visible hazard warnings. Not suited for applications needing master-keyed systems or electronic access logging.

Questions about this item

How do I fit the 3/16 in shackle through the lockout point and what step is often missed?

Insert the stainless-steel shackle through the hasp or isolation point, snap the body shut, then turn the key to lock; the key-retaining mechanism means the key cannot be removed until the padlock is locked, so forgetting to turn the key fully leaves the shackle unsecured.

What part of this lockout padlock will need replacement first with regular use?

The included labels on the yellow thermoplastic body wear or fade before the shackle or cylinder, so plan to replace the identification labels when they become illegible.

Which limit appears first when the padlock is left in a damp industrial area for months?

The thermoplastic body resists corrosion but prolonged moisture exposure can degrade the label adhesive and printed text before the stainless-steel shackle shows any rust.
