Replacing the valve box cover with the right fit is no longer a hassle with the 6 in. SureFit Round Universal Valve Box Lid. Designed for compatibility, the valve box cover works with a wide range of 6 in. and 7 in. valve box brands to provide a proper fit. Durable gripper prongs bend and flex but won't break, using tension to anchor to the inside of the box for a secure hold. The reinforced cover is made of high-density polyethylene (HDPE) treated with UV inhibitors to prevent fading and cracking. The easy lift tab and knockout finger holes make it easy to remove the lid by hand without any tools. Structural ribs provide support without getting in the way of the components inside the box. No matter what brand of valve box, you've got it covered with the SureFit Universal Lid.
