Overview for the Trumbull 367-9153 Valve & Curb Box Cleaner. The Trumbull Valve & Curb Box Cleaner gets dirt, stones, and other foreign objects out from valves and curb stops. This makes it easy for professionals to access them at work. Simply squeeze the level of the cleaner to open jaw, and release to close. This Trumbull heavy-duty hand tool is specially made for cleaning out 2 ½” and 3” Buffalo curb boxes as well as 4 ¼” and 5 ¼” Buffalo valve boxes – without the need for excavation. And unlike other cleaners that can “over-open” and become disengaged, the Trumbull curb box cleaner’s unique jaw design prevents these from happening. The Trumbull valve cleaner is built for long life and abusive handling. It has carbon steel jaws, EDP-coated components for corrosion resistance, and zinc chromate plated handle and tee.
