The Master Lock Seal Tight Handle–Off Ball Valve Lockout delivers an innovative design that eliminates the risk of valve reactivation with the removal of the handle. Simply remove and store handle and cover the valve stem for a secure lockout. The ML468L offers a universal fit that effectively lock out all valves from 3/8" to 4" (0.9cm x 10.1cm) and works in virtually all valve installations (metal and PVC valves, insulated pipes, pipes mounted close to a wall or ceiling and valves with tight access due to proximity to other valves or pipes). The Seal Tight Handle–Off Ball Valve Lockout is easy to use and simple to apply with an intuitive wrapping strap and locking mechanism and it includes write-on erasable labels in English, French & Spanish. This valve lockout is a lightweight, flexible device that can easily be carried to the job and then folded for compact storage in safety toolboxes and performs effectively to withstand corrosive environments and operates in extreme conditions (temperature range: - 40°F to 250°F (-40°C to 121°C)).
