Master Lock 411KAS3GRN Lockout Padlock Keyed Alike Green

Safety Lockout Padlock for Energy Isolation

This Master Lock padlock is designed for lockout-tagout procedures where equipment must be secured against accidental energisation. The green thermoplastic body resists chemicals and provides clear visual identification on site. It is supplied keyed alike with two keys and non-removable key retention for controlled access. Safety officers and maintenance teams use it to isolate valves, breakers and machinery during service work.

Thermoplastic Body With Hardened Steel Shackle

The 1/4 in hardened steel shackle withstands cutting force while the thermoplastic body absorbs impact without conducting electricity. Chemical resistance allows use in harsh plant environments where solvents or oils are present. The 13/16 in horizontal and 1 1/2 in vertical clearances fit standard hasps and lockout devices. Non-removable key design prevents the key being withdrawn while the shackle remains open.

Keyed Alike Configuration Determines Multi-Point

Every padlock in the set operates from the same two keys, so one authorised person can secure multiple isolation points quickly. Buyers who need each lock to have a unique key for individual accountability cannot use this keyed alike model. The fixed keying is set at the factory and cannot be re-keyed on site.
