Safety padlock for lockout procedures

The Master Lock Zenex padlock is a non-conductive safety device designed for lockout and tagout applications. Its green thermoplastic body and plastic shackle provide electrical insulation during maintenance work. The keyed-different cylinder ensures each lock operates with a unique key for individual accountability.

Check shackle dimensions before ordering

Verify that the 13/16 in horizontal shackle clearance fits the hasp or isolation point on your equipment. The 1/4 in shackle diameter must match the hole size on your lockout device. Confirm the 1 1/2 in vertical shackle clearance provides enough reach for your specific application.

Non-conductive materials reduce thermal risk

The thermoplastic body and plastic shackle do not conduct heat or electricity under normal lockout conditions. No moving parts generate noise during operation. The key-retaining feature prevents the key from being removed while the shackle is open, maintaining the safety circuit.

Questions about this item

Does the padlock come with keys or must they be ordered separately?

The padlock is supplied keyed different with a standard key and the key is non-removable so it stays in the lock when unlocked.

Which shackle clearance should I choose for a standard lockout hasp?

The horizontal and width-across-shackle clearance is 13/16 in and the vertical clearance is 1 1/2 in; match those dimensions to your hasp or chain link.

How does the non-conductive thermoplastic body perform on a live electrical panel?

The body and shackle are both plastic and rated non-conductive, so the lock will not create a conductive path when applied to energised equipment.
