Safety lockout padlock for authorised personnel

The Master Lock 410KAYLW is a yellow thermoplastic padlock designed for lockout procedures where only designated staff hold the key. Its 1 1/2 inch body width and 1/4 inch metal shackle fit standard industrial hasps and energy-isolation points. The keyed-alike cylinder means every lock in the set opens with the same key, simplifying key management for maintenance teams.

Key-retention limits key loss during procedures

The non-removable key cannot be withdrawn while the shackle is open, so the lock cannot be left unlocked by mistake. This mechanical constraint only works when the key is fully turned; it does not prevent the shackle from being closed without the key if the cylinder is not engaged. Users must verify the key is trapped before walking away.

Chemical-resistant body suits harsh plant

The thermoplastic housing resists common industrial chemicals, protecting the internal cylinder from corrosion that could jam the mechanism. This resistance is the single specification that determines whether the padlock survives the intended service area; locks without it may seize in wash-down or chemical-processing zones.

Questions about this item

Should I choose the keyed-alike version or a different keying option for multiple locks?

This padlock is supplied keyed alike, so every unit opens with the same key — ideal when one person manages several lockout points.

What does the 1 1/2 inch shackle height mean when the lock is on a hasp?

The 1 1/2 inch vertical clearance lets the shackle pass through standard hasps and valve handles while leaving enough room for the thermoplastic body to sit flush.

How does the 1/4 inch shackle diameter limit what I can lock?

A 1/4 inch metal shackle fits most industrial lockout hasps and chain links, but will not pass through smaller-diameter holes or tight cable loops.
