Always fits: our Universal Valve Lock V500. Valve handles come in countless different shapes. Our Universal Valve Lock V500 fits all, as it can be attached to all different types of valve handles. How does it work? The clamping area surrounds the handle and is adjustable in height. This allows it to fit all sizes and shapes of ball valve handles. The valve lock provides a hanging point for a cable lock. This cable lock connects the valve handle through the hanging point to a fixed counterpoint, ensuring that the ball valve is secured and protected from unauthorized access.
