Lockout Padlock for Shared Access

The Master Lock 410KAS3BLK is a keyed-alike thermoplastic padlock designed for lockout programmes where several workers use the same key. Its black body and open steel shackle suit industrial panels and energy-isolation points.

Chemical-Resistant Thermoplastic Body

The lock body resists common chemicals found in maintenance areas. A non-removable key prevents accidental loss during use, and the included danger header labels reinforce on-site safety messaging.

Open Shackle with Standard Keyway

The 13/16 in horizontal and 1 1/2 in vertical clearances fit most hasps and valve handles. Two keys and labelling tags are supplied, so teams can identify circuits without extra hardware.

Questions about this item

Should I choose the keyed-alike set or look for a different keying option?

The 410KAS3BLK is supplied as a keyed-alike three-pack, so every padlock opens with the same two included keys — choose this when you want one key for multiple lockout points.

What does the 13/16 in horizontal shackle clearance mean when I fit the lock to a hasp?

It gives you 13/16 in of space between the shackle legs, wide enough for standard lockout hasps and chain links while still fitting tight hardware.

How does the thermoplastic body hold up against chemicals in an industrial area?

The black thermoplastic body is listed as chemical-resistant, so it resists common solvents and cleaning agents without cracking or degrading.
