StoneAge’s BOP 622 back-out prevention device for pipe cleaning with the AutoBox ABX-500 hose tractor reduces overall weight for quick setup, secure anchoring and safe back-out prevention. It features a flexible 7-foot stainless steel snout that shields the hose and enables the tractor to exert up to 200 ft-lb of push force on the hose. The attached back-out preventer stops the tool from exiting the pipe and can be used independently of the snout when needed. 866/795-1586; www.stoneagetools.com.
