Lockout Padlock for Safety Procedures

The Master Lock 410 lockout padlock uses a red thermoplastic body and a hardened steel shackle. It is keyed alike so one key opens every padlock in the set. Safety teams use it to isolate energy sources during maintenance.

Simple Keyed-Alike Installation

Each padlock arrives with a non-removable key that cannot be pulled out while the shackle is open. Workers snap the shackle onto the hasp and turn the key. The only common issue is forcing the key before the shackle fully seats.

Verify Your Lockout Points First

Check that the 13/16 inch horizontal and vertical clearances fit your switch or valve handles. Confirm the 1/4 inch shackle diameter matches the hole size on your equipment. Ensure the red colour coding matches your site safety standard.

Questions about this item

How can I confirm the Master Lock 410 padlock is functioning correctly after installation?

Verify the shackle opens only with the correct key, locks automatically when pushed shut, and the key cannot be removed while the shackle is open.

What components are included with the Master Lock 410 padlock and are extra keys available?

The lockout padlock body and shackle are supplied; the keyed-alike configuration means multiple locks share the same key, so additional keys are not required per unit.

Which Master Lock 410 variant should I select for a red thermoplastic body with 1/4-inch hardened steel shackle?

Choose the 410 model with red body colour, thermoplastic construction, 1/4 in shackle diameter and hardened steel shackle material as detailed in the specifications.
