Replace a damaged or missing cover for a valve box with the 6 in. Round Standard Series Valve Box Cover, compatible with the 107B box and other 6 in. round Standard Series valve boxes. This lid works with the access box to protect underground irrigation and sprinkler system components from the elements, pedestrian traffic, lawn care equipment, and potential vandalism. The purple cover is built for durability with structural reinforcing ribs, and markings indicate "RECLAIMED WATER." The overlapping lid prevents dirt and debris from entering the valve box. Bayonet twist-lock lid features two finger slots, making it easy to remove or secure onto the box. The irrigation box lid is made of high-density polyethylene (HDPE) treated with UV inhibitors.
