The Chicago Pneumatic CP 0003 and CP 0004 backfill tampers are designed to compact soil around existing infrastructure, such as foundations, and to compact backfill in trenches. The CP 0003 weighs 30 pounds, has a length of 4.3 feet and air consumption of 133 gpm. The CP0004 weighs 42 pounds and air consumption of 206 gpm. The butts on both tampers are secured to the lower end of the piston rod. Models with an aluminum butt are held with a clamp screw for quick, easy replacement. A valve in the back head of the assembly controls the reciprocating movement of the piston while the hand valve controls the airflow. Both backfill tamper models can be easily operated by one person and are suited for use by trenching companies, general contractors, municipalities, cable layers, utilities and more. www.cp.com/usen/
