Master Lock - Electrical Lockout Devices
Master Lock Rotating Electrical Plug Lockouts
Outward / Inward Rotation Allows for Easier Application and Storage
The Master Lock electrical plug lockout device surrounds the electrical plug, protecting against accidental reconnection. This unique, patent-pending rotating design allows for easier installation in confined spaces. In addition, each size rotates into itself for compact storage in safety tool boxes.
Electrical plug lockouts come with high-visibility permanent safety labels that can be written on to identify the responsible person. They can then be erased and used for the next job.
Master Lock electrical lockouts have tough, lightweight, dielectric Xenoy thermoplastic bodies that can withstand chemicals and perform effectively in extreme conditions.
Rotating Electrical Plug Lockouts are available in two sizes: one that fits most 110 and many 220 volt plugs and a larger size that fits most 220 and 550 volt plugs.

For bigger plugs, choose the 488 (fits 3"-6" with a cord diameter up to ¾", which fits most 220-550 volt plugs).
