Model 411 lockout padlock
The Master Lock #411 is a red safety lockout padlock with a 3-inch high body and a 1 1/2-inch shackle. It is keyed differently for individual access control in lockout/tagout procedures. The bright colour aids visual identification on industrial equipment. It suits maintenance teams and authorised personnel securing energy isolation points.
Sustained exposure resistance
The lock body and shackle are built to withstand the environmental conditions found in industrial settings during extended lockout periods. The high body design protects the internal mechanism from debris and physical impact over time. The keyed-different cylinder maintains reliable operation through repeated locking cycles. It is not for users needing keyed-alike convenience or master-keyed systems.
