Master Lock 410 Keyed-Alike Set
This Master Lock 410 pack contains twelve yellow thermoplastic padlocks keyed alike so one key opens every lock. The set is intended for lockout/tagout programmes where multiple energy-isolation points must be secured by the same authorised person.
Installing the 410 padlocks
Each lock has an open steel shackle with 13/16 in horizontal and 1 1/2 in vertical clearance; simply insert the shackle through the hasp or isolation point and snap the body shut. The non-removable key feature prevents the key from being withdrawn while the shackle is open, reducing the chance of leaving a lock unlocked.
Check your existing setup
Verify that the 1/4 in shackle diameter fits the holes on your lockout devices, breaker toggles or valve handles. Confirm that the 1 3/4 in body height and 3/4 in thickness allow the lock to sit flush in the space available, and ensure the yellow colour matches your site coding standard.

Questions about this item
How can I confirm the 410 lockout padlock is functioning correctly after setup?
Insert one of the two included keys, turn to retract the 1/4 in steel shackle fully, release the key — it stays trapped — then turn again to extend the shackle until it clicks; the thermoplastic body should show no cracks and the yellow Danger header must remain legible.
What comes in the 12-pack box and what must I purchase separately?
The box contains twelve yellow thermoplastic padlocks, each with a 1/4 in steel shackle, non-removable key cylinder and two keys; all units are keyed alike. No additional keys, labels or lockout hasps are included.
Which version of the 410 lockout padlock should I choose for a team that needs identical keys?
Select the keyed-alike 12-pack; every padlock in the set operates with the same two keys, eliminating the need to manage multiple key codes across the group.
