Onsite Systems + Get AlertsDamage-resistant DuraFiber lids from Orenco Systems fit most ribbed PVC and HDPE riser pipes. The 11-pound, 24-inch-diameter nonskid lid (30-inch available) is made of resin-infused, UV-resistant fiberglass fabrics.
“The nonskid material is 100 percent resin,” says Eric Ball, vice president of product development. “Resin provides very good UV resistance. Once it oxidizes you get a protective layer so the sun doesn’t break down the laminate.”
The lids, which have a 20,000-pound breaking strength, include a flat-style flange for flush-to-grade installation and cored centering ring for easy alignment and snug fit. A urethane gasket helps ensure a watertight seal.
“All the lids I’m aware of have a flange that’s vertical on the outside edge, usually an inch or a couple inches tall, that ends up being in the dirt or landscaping,” Ball says. “If the lid hasn’t been taken off for a long time, you’ve got grass growing and you have to get a shovel and dig around it. Then when you put it back in you have to excavate even more. Whereas if you have a flat-style flange it’s not buried in the dirt.”
Other features include a customizable 6-inch center insert and molded-in “caution” statement: Always keep fastened; Do not enter.
“We can take any artwork and put it into the center of the lid,” Ball says. “We’ll do the artwork or it can be provided. Typically it’s a logo and phone number.”
Four tamper-resistant 5/16-inch stainless steel flathead screws and hex wrench are included. Optional 2- or 4-inch insulation can be preinstalled or added in the field with a hardware kit. The lids are available in standard green and three landscape patterns: grass, river rock and bark. 800/348-9843; www.orenco.com.
