These low profile cam push clamps are activated by turning the cam handle which extends the piston for fast accurate clamping. The spring loaded piston retracts when the cam handle is released for loading and unloading parts. The piston is tapped for installing a clamping tip. Mounts from the top with two mounting holes. Part numbers ending with R have a clockwise clamping direction and part numbers ending in L have a counter clockwise clamping direction. The body and piston are made from SAE-1045 alloy steel. The handle is made from SAE-4140 alloy steel. Black oxide finish.
