Safety padlock for lockout procedures
This green thermoplastic padlock is keyed alike so one key opens every unit in the set. It is intended for maintenance teams and safety officers who need consistent key access across multiple isolation points. The non-removable key design prevents the key from being left in the lock while the shackle is open.
Simple keyed-alike installation
Each padlock arrives with two keys and an included label for on-site identification. The standard keyway allows immediate use without re-keying tools or specialist training. The main issue occurs when buyers expect individually keyed locks and discover all units share the same key code.
Limits of a single key code
A keyed-alike set cannot restrict access to specific workers or zones because every lock opens with the same key. The thermoplastic body resists common chemicals but is not rated for high-security physical attack. Users needing unique keys per lock or higher tamper resistance must choose a different specification.

Questions about this item
How can I verify the 410 padlock is working correctly after setup?
Insert one of the two included keys, turn to retract the 1/4 in steel shackle fully, then release — the non-removable key feature ensures the key stays in the locked position until turned again.
What comes with the 410 lock and what must I purchase separately?
The package includes the green thermoplastic body, 1 1/2 in steel shackle, two keys and labels; no additional components are required for basic lockout use.
Which version of the 410 should I choose for a keyed-alike green lockout set?
Select the 410KAS3GRN model — it provides a green thermoplastic body, 1/4 in shackle diameter, 1 1/2 in vertical clearance and keyed-alike operation in a single unit.
