It is designed to instantly release vacuum with the push of a lever. A detachable tripod design lets it stand on its own, granting hands-free operation. The shutter design allows the operator to regulate airflow as needed. It is designed for 4- and 6-inch flex hose. 714/632-8198; www.southlandtool.com.
