The Saf-T-Guide Roller from Southland Tool keeps contaminated sewer water from splashing up from the manhole. It is made of aluminum and incorporates clear, removable Lexan side plates that protect the operator from spray and mist. The plates are 3/8-inch thick with rubber trim around the edge that won’t come off. The center roller is made of durable nylon. The end lift plate allows the operator to insert hose with any size nozzle. Units are available for 24- or 36-inch manholes. 714/632-8198; www.southlandtool.com.
