The Manhole Edge Protector from Perma-Liner Industries is made with a highly visible safety orange that helps identify the site and the open manhole, eliminating potential hazards. The 360-degree edge protection also eliminates the top-edge roller and top-wide tiger tail that can allow the cable to slip off the roller. The interior 3.5-inch flange holds back debris and any loose infrastructure from falling into the manhole. It is made with ABS 3/16 plastic, which is durable and withstands temperatures from 40 degrees below zero to 180 degrees F. The Manhole Edge Protector leaves the manhole completely open, providing accessibility and visibility while also protecting the camera and jetter lines. 866-336-2568; www.perma-liner.com.
