Aluminum Super Tube digging tubes from Super Products are ideal for hydroexcavators and sewer cleaners used on challenging job sites. They are constructed of thick, high-strength, heat-treated alloy, making them less prone to denting during handling and severe use. Available in 6- and 8-inch diameters and a variety of lengths up to 20 feet, they have custom cast ends that enable them to be easily interchangeable with other Super Tubes. 800/837-9711; www.superproductsllc.com.
