Master Lock 427 Labeled Lockout Hasp

The Master Lock 427 is a labeled lockout hasp designed for industrial safety procedures. It allows up to five padlocks to be applied simultaneously, enabling multiple workers to isolate a single energy source. The unit features a snap-on closure for quick application on standard lockout points.

Snap-On Closure With 3/8 Inch Shackle Limit

The single specification that decides fit is the maximum padlock shackle diameter of 3/8 inch. The closed jaw hole measures 2 1/8 inches, and the snap-on mechanism secures the hasp without additional tools. Verify your padlock shackles and lockout point dimensions against these figures before purchasing.

Stainless Steel Construction Resists Corrosion

Built from stainless steel with a red finish, the hasp withstands harsh environments and chemical exposure without degrading. The integrated English label reads "Danger Do Not Operate" for clear visual warning. At 7 inches long, it remains rigid during extended lockout periods, maintaining secure isolation for the duration of maintenance work.

Questions about this item

How does the five-lock capacity work when the hasp is on an energy-isolation point?

The snap-on hasp accepts up to five padlocks simultaneously so each authorised worker can apply their own lock and the equipment cannot be re-energised until every lock is removed.

What does the snap-on closure mean for daily lockout procedures?

The snap-on jaw closes quickly around the isolation point without threads or tools, then each padlock secures the hasp in place for a fast, repeatable lockout.

What are the overall dimensions so I can confirm it fits my panel space?

The hasp measures 7 in overall length by 2 7/8 in overall width with a 2 1/8 in closed jaw hole.
