Lockout padlock for safety procedures

The Master Lock 410KARED is a lockout padlock built for industrial safety programmes. Its thermoplastic body resists chemicals and carries a red Danger header. The shackle is metal with a 1/4 in diameter and 1 1/2 in height. All units in the set are keyed alike using a standard key that cannot be removed while the shackle is open.

Thermoplastic body under chemical exposure

The body material withstands repeated contact with common industrial chemicals without degrading. The non‑removable key feature prevents accidental unlocking during a lockout sequence. The keyed‑alike arrangement lets a single key control every padlock on a work site, reducing the number of keys a supervisor must carry.

Shackle dimensions limit attachment points

The horizontal and vertical shackle clearances are each 13/16 in, and the width across the shackle is also 13/16 in. These fixed openings restrict the padlock to hasps, chains or valve handles that fit within those measurements. Buyers who need a larger shackle gap or a different keying system will need another solution.

Questions about this item

Does the 1/4 in shackle diameter resist cutting during extended outdoor use?

The 1/4 in metal shackle provides standard physical security; the lockout padlock is designed for safety identification rather than high-security cutting resistance.

What key system is needed to operate this padlock?

The lock uses a standard keyed-alike cylinder; one key opens every padlock in the same keyed-alike set, and the key is non-removable when the shackle is open.

Will the thermoplastic body withstand contact with oils and solvents in a maintenance area?

Yes, the red thermoplastic body is listed as chemical resistant, making it suitable for environments with oils, solvents and other common industrial chemicals.
