Brady’s Plug Valve Lockout is the first lockout device to easily and effectively secure a manually-actuated plug valve with a stem diameter from 55.56 to 63.50 mm. The base of the lockout device can remain in place once applied, and generally does not interfere with valve activation by wrench or removable handle. The device is compact in size, yet highly-visible and easy to use and made of durable polypropylene.
