A radial grip remote control for the operation of abrasive blast machines. The handle of the grip is permanently attached to a linear bearing. The bearing utilizes the abrasive blast hose as a journal, and may be rotated manually by adjusting the radial position of the handle. The inside diameter of the bearing is adjustable. The adjustment is intended to allow the bearing to rotate freely about its journal (hose), and to cause seizure of the bearing to this journal when the hose is pressurized. The steel handle acts as a protective housing for a positive shut-off type valve which is internally installed. The remote control is designed to be ergonomically accommodating and to increase the safety of abrasive blasting operations. The base of the handle comprises a female connecting socket for adaptation to automated or remotely operated abrasive blast systems.
