Rotating Gate Valve Lockout offers outward/inward rotation for easier installation and storage. When in place, the lockout prevents the valve handle from being inadvertently turned. Medium size fits 4" to 6-1/2" diameter handles. Unique, patent-pending rotating design allows easier installation in confined space applications. Valve cover surrounds the valve operating handle to protect against accidental valve opening. Center knockout can be removed for rising stem gate valves. Included high-visibility, permanent safety labels in English, French and Spanish can be written on to identify the responsible person, and then erased for the next job. Tough, lightweight, dielectric Xenoy thermoplastic bodies withstand chemicals. Valve cover performs effectively in extreme conditions in temperatures ranging from negative 50 degrees Fahrenheit (negative 46 degrees Celsius) to 350 degrees Fahrenheit (177 degrees Celsius).
