Lockout padlock for group access

The Master Lock 6121 is a keyed-alike padlock built for lockout programmes where multiple workers need the same key. Its laminated steel body and boron-alloy shackle suit outdoor industrial environments.

Sustained outdoor exposure

A weather-tough cover protects the mechanism from rain and dust during extended use on site. The 5/16 in shackle diameter and boron alloy construction resist cutting attempts over long periods.

Steel body with open shackle

The 1 in thick laminated steel body provides a solid feel in the hand while the open shackle design allows quick attachment to hasps or chains. Orange coating makes the lock visible in low-light conditions.

Questions about this item

Does the 5/16 in boron alloy shackle stay easy to operate after days of outdoor exposure?

The lock has a weather tough cover and a laminated steel body designed for outdoor use, so the shackle action remains reliable in rain and temperature swings.

What key do I need to open the Master Lock 6121 if I order several?

The padlocks are supplied keyed alike, so one key fits every unit in the set.

Will the 1 1/8 in shackle clearance fit the same hasp holes as my older steel padlocks?

The shackle diameter is 5/16 in and the inside height is 1 1/8 in, matching common industrial hasp dimensions used with older steel locks.
