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 Non-removable key design prevents the key being withdrawn while the shackle remains open.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.

Questions about this item
Does the hardened steel shackle on this 1/4 in padlock get hot or noisy when left locked all day?
The padlock has no moving parts that generate heat or noise; the thermoplastic body and hardened steel shackle remain passive during continuous use.
What keys or tools must I already have to open the Master Lock 411KAS3GRN?
Two standard keys are included in the pack; no additional keys or tools are required for operation.
Will the 13/16 in shackle clearance fit the older hasp brackets I already use?
The vertical and horizontal shackle clearances are both 1 1/2 in and 13/16 in respectively, so compatibility depends on your existing hasp slot dimensions.
