Lockout padlock for keyed-alike safety systems

This Master Lock 410KABLU padlock is built for lockout programmes that require every lock in a set to open with the same key. Its blue thermoplastic body resists chemicals and measures one and a half inches wide with a one and three quarter inch height. The open shackle is one quarter inch thick and provides one and a half inches of vertical clearance.

Thermoplastic body resists chemicals

The non-conductive shell handles exposure to solvents and cleaning agents without corroding. A standard keyway and non-removable key design keep the key captive while the lock is open, preventing loss during shift changes. Metal shackle construction adds cut resistance while the body stays light.

Sustained use keeps key captive and shackle aligned

Under repeated lockout cycles the key remains in the cylinder until the shackle is secured, so operators cannot walk away with the key. The open shackle geometry maintains consistent alignment through hundreds of engagements. Chemical resistance preserves body integrity in harsh plant environments.

Questions about this item

How do I install the 1 1/2 in thermoplastic body on a hasp, and which shackle clearance do people mix up?

Insert the 1/4 in metal shackle through the hasp and snap the body shut; the key stays trapped inside. The error is confusing the 13/16 in horizontal gap with the 1 1/2 in vertical gap — measure the hasp slot against the vertical figure.

What part will need replacement first on a 410 keyed-alike set used daily in a chemical area?

The shackle is metal while the body is chemical-resistant thermoplastic; the shackle will show corrosion or wear before the body degrades, so plan to replace the padlock when the shackle no longer slides freely.

At what point does the non-removable key become a problem during sustained lockout procedures?

Because the key cannot be removed while the padlock is open, every lockout cycle requires the authorised holder to be present; the limit appears when shift changes or multiple isolation points exceed the number of keys issued.
