Lockout Padlock Keyed Alike

The Master Lock 410KAS12RED is a thermoplastic lockout padlock supplied in a 12-pack with every unit keyed alike. Safety teams use it to isolate energy sources during maintenance so that a single key opens all locks on a job site.

Replaces Mixed Key Sets

A keyed-alike set removes the need to track individual keys for each lockout point, cutting the time spent searching for the right key during shift changes. The jump is worth it when a crew services multiple panels or machines on the same shift and needs one key per person.

Sustained Industrial Use

The thermoplastic body resists chemicals and corrosion while the steel shackle withstands repeated locking cycles in harsh environments. Non-removable key design prevents the key from being left in the padlock, so the lock stays secure through long lockout periods.

Questions about this item

What shackle clearance does the 410 padlock provide for a hasp or chain link?

The open steel shackle gives 13/16 in horizontal and 1 1/2 in vertical clearance with a 1/4 in diameter.

How are the two included keys used during initial lockout setup?

Both keys operate every padlock in the keyed-alike set; the non-removable key feature keeps a key trapped in the cylinder until the shackle is locked.

When should the red thermoplastic body or steel shackle be replaced?

Replace the padlock if the body shows chemical damage, cracks, or the shackle is bent, corroded, or no longer latches securely.
