Keyed-different padlock Master Lock series 3, laminated steel

Offered notably in yellow, green, black and white; choose your colour in the format table below.

The Master Lock series 3 is a safety padlock: a laminated steel body, a hardened steel shackle and one key per padlock. It is used to lock energy-isolating devices during lockout.

Which key type should you choose?

This padlock is keyed different: each padlock has its own key, and keys differ from one padlock to the next. It is the choice that brings the most security for personal lockout, since each worker's padlock has its own key. The same series also exists keyed alike: the black padlock (CA1M), model 3KA, is used for access control, for example on the tool chests and cabinets of a vehicle fleet, and never for a worker's personal protection.

Warning: a keyed-alike padlock must never be used for a worker's personal safety lockout (energy isolation). If someone else holds the same key, they could remove the padlock while the worker is exposed, putting their life at risk. For personal protection, choose a keyed-different padlock. Keyed-alike padlocks are better suited to access control, for example on a job site, so that all foremen can open containers, site trailers and tool cages with a single key.

Care and maintenance of the padlock

The manufacturer lists severe weather and extreme environments among the environments for this series. Its padlock care guide recommends cleaning and lubricating the padlock every 3 to 6 months, and every 3 months in extremely dusty or corrosive environments: blow the dust out of the keyway and shackle openings with compressed air, apply a small amount of PTFE lubricant to the keyway and the shackle, open and close the padlock several times with the key, then wipe off the excess and let it air dry. Never use dry graphite or a silicone lubricant.
