The DustROD ER (Extended Reach) provides an additional 58" of reach. Perfect for jobs that require a few extra feet of reach. You will use your DustROD ER for everything from stinging insects, to mechanical rooms, high ceilings, pipe chases, eaves and overhangs, behind fridges, freezers, pallets, and equipment. With the DustROD ER you receive a 22" section with stainless steel dusting nozzle and elbow each rotating 360 degrees to reach any angle, and two 18 inch extensions. It's like having 3 DustRODs in 1.
