Description

The Hollow Hydraulic Cylinder Jacks boast an ingenious design that enables them to offer both a pushing and a pulling motion. The central hole can be used with various screws, roads, cables, and pullers.
The hollow hydraulic cylinder jacks can be used just like our other hydraulic cylinders. Still, the addition of the central hole gives them a handy extra function with many possible applications.
By inserting a screw, rod, or cable into the cylinders hole, you can create a solid pulling motion in addition to the standard pushing/lifting function. Collar threads make the hollow jacks easy to use, and a baked enamel finish makes them very robust and increases corrosion resistance.
