The Trydent 80 small-pipe cutting system from TRY TEK Machine Works allows reinstatement of interior or exterior relined pipes from 3 to 6 inches in diameter. Operators can access pipe systems through clean-out ports or rooftop vent pipes. Buildings where tenants or operations cannot be disturbed are ideal prospects. It can be used to reinstate an entire vertical waste pipe from a single access point. Its small, powerful cutting head can maneuver around 90- and 45-degree elbows and navigate multiple bends and turns. Its reach extends up to 100 feet and its narrow 23-inch width enables easy access through doorways. It can be used to reinstate lateral waste pipes connected to the sewer main at ground or basement level. 717/428-1477; www.trytek.com.
