Safety Padlock for Lockout Procedures

The Master Lock 410 Zenex padlock is built for industrial lockout and tagout programmes. Its red thermoplastic body resists chemicals and carries a danger header for clear identification. The shackle is steel with a 1 1/2 in height and 1/4 in diameter. Each unit ships with two keys and labels for on-site marking.

Keyed Alike Operation and Durability

All six padlocks in the set are keyed alike so a single key opens every lock in the group. The non-removable key feature prevents the key from being withdrawn while the shackle is open, reducing accidental unlocking. The thermoplastic body and steel shackle withstand harsh environments without corroding.

Compact Dimensions for Tight Spaces

Horizontal shackle clearance measures 13/16 in and vertical clearance is 1 1/2 in, allowing fitment on crowded breaker panels or valve handles. The 3/4 in body thickness and 1 1/2 in width keep the profile slim. Labels are included for quick hazard identification during maintenance shifts.

Questions about this item

How do I install the Master Lock 410KAS6RED on a hasp, and what clearance mistake do people make?

Insert the 1/4 in steel shackle through the hasp; the 13/16 in horizontal and 1 1/2 in vertical clearances must both fit, so measure the inside gap before you buy.

What part of this lock will need replacement first?

The two included keys wear faster than the thermoplastic body; order extra standard keys keyed alike to avoid downtime.

What limit appears first when the lock stays outdoors in chemicals?

The red thermoplastic body resists chemicals, but the 1/4 in steel shackle will show surface corrosion before the body degrades.
