Master Lock 410 Lockout Padlock Keyed Alike Thermoplastic Black

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.
