The 24-inch DuraFiber Lid from Orenco Systems is made of resin-infused fiberglass fabrics for durability and damage resistance with breaking strengths in excess of 20,000 pounds. It fits most ribbed PVC and HDPE riser pipe and weighs 11 pounds. It has a flat-style flange, allowing flush-to-grade installation; a cored centering ring, providing an easily aligned, snug fit; and a soft urethane gasket to help provide a watertight seal. Lids include four 5/16-inch stainless steel flathead screws and a hex wrench. Optional 2- or 4-inch insulation is available, which can be preinstalled at the factory or installed on site with a hardware kit. They have a nonskid surface with customizable center insert, along with a molded-in “Caution” statement. In addition to the standard green color, they’re available in three landscape patterns – grass, river rock and bark. 800/348-9843; www.orenco.com.
