Lockout padlock for safety procedures

The Master Lock 410 padlock uses a thermoplastic body with a hardened steel shackle. It is keyed alike so one key opens every lock in the set. The non-removable key prevents the shackle from being left unlocked. Chemical resistance suits industrial environments.

Keyed alike convenience and physical limits

A single key operates multiple 410 units, reducing the number of keys a team must carry. The 1/4 inch shackle diameter fits standard lockout hasps and valve covers. The 13/16 inch horizontal and 1 1/2 inch vertical clearances limit use on oversized fittings or thick chains.

Mechanical push button operation constraints

The mechanical push button cylinder has no electronic components, so it cannot integrate with access control software or audit trails. It requires physical key management and cannot be reprogrammed remotely. Users needing electronic logging or temporary codes must choose a different system.

Questions about this item

Will the 1/4 in hardened steel shackle fit the 13/16 in clearance on my existing lockout hasps?

The shackle diameter is 1/4 in and both horizontal and vertical clearances are 13/16 in, so it matches standard hasp openings of that size.

How do I confirm the keyed-alike set works on every padlock after installation?

Insert the supplied key into each lock; it should turn smoothly and retract the shackle on all units because they are keyed alike.

Does the package include keys or must I order them separately?

Keys are included with the keyed-alike set; no separate key purchase is needed.
