Replace a damaged or missing cover for a valve box with the 6 in. Round Standard Series Valve Box Cover, compatible with the 106B valve box. 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 green cover is built for durability with structural reinforcing ribs, and markings indicate "ICV” to identify irrigation control valve components. Snap-in overlapping lid has a finger hole to remove the lid for inspection and maintenance. The irrigation box lid is made of polypropylene (PP) treated with UV inhibitors.
