When you need a compact hydraulic wedge spreader for tight spaces the WR5 is the optimum choice. This single-acting tool uses powerful hydraulic force to expand up to 3.7" (94mm) and retracts with a spring return system.
Please note that the maximum load capacity is 1-ton (8.9kN), and the maximum system pressure must be limited to half the rated pressure (5000 psi 350 bar).
