Abstract
A telescoping lockout device for encasing a gate valve, electrical connection, or similar apparatus, for the purpose of preventing unauthorized access and tampering with the apparatus. The lockout device is comprised of two nested half cylinders attached to one another through T slot that provides for telescoping of the device between an open position, where one half cylinder is nested within the other, and a closed position, where the half cylinders form a cylinder. The T slot provides a rail on one half cylinder that inserts into a track on the other half cylinder. At the ends of the T slot track and rail is an interlock. The lockout device also has locking tabs that, when the lockout device is placed in the closed position, provide overlapping locking openings into which a lock, such as a padlock, can be inserted.
