Lockout Padlock for Electrical Safety

This Master Lock 406KAS3GRN padlock is built for lockout-tagout procedures where non-conductive materials are required. The thermoplastic body and plastic shackle provide dielectric protection during electrical maintenance. It suits maintenance teams and facility managers who need consistent keying across multiple lockout points.

Sustained Exposure to Industrial Conditions

The thermoplastic body resists chemicals, moisture and temperature variation found in industrial environments without corroding or conducting electricity. Keyed-alike cylinders allow a single key to open every padlock in the set, reducing key management during extended shutdowns. Non-removable key design prevents the key from being left in the lock while equipment is energised.

Verify Your Lockout Requirements Before Ordering

Confirm that a 1/4-inch shackle diameter fits your hasp or lockout device and that 13/16-inch horizontal and vertical clearances meet your isolation points. The keyed-alike configuration means all units in the pack share the same key code; buyers needing unique keys per lock should select a different option. Included danger labels and two keys per padlock support immediate deployment.

Questions about this item

How much heat does the Master Lock 406KAS3GRN generate when left locked on an energised panel all day?

The lock body and shackle are non-conductive thermoplastic and plastic, so they produce no heat and do not transfer electrical energy.

What key must I already have to open this lock?

The padlock is supplied keyed alike with two standard keys included; no separate key is required.

Will the 1/4 in plastic shackle fit through the 13/16 in hasp on my older lockout station?

Yes, the 1/4 in diameter shackle and 13/16 in horizontal clearance allow it to pass through standard hasps of that size.
