The Super Combo Cable Brushing System consists of six brushes, one flexible cable, and one solid-core cable. The flexible cable is available in 15- and 25-foot lengths, and the solid-core cable is available in 20- and 33-foot lengths. The set includes nylon brushes in 8-, 12-, and 18-inch sizes and silica carbide brushes in 8-, 12-, and 18-inch sizes. The flexible cable and the appropriately sized brush can be used to clean ductwork that has drops and turns, says the manufacturer, while the solid-core cable can be used with the appropriate brush to clean larger main trunk lines.
