This hydraulic spreader is rated at a full 1-ton capacity at 10,000 PSI and that’s enough for a wide variety of jobs. Working in tight spots is no problem—it needs only a 9/16" clearance to engage the jaws. With a big 4" spread, it’s ready for a variety of applications: straightening work, removing dents and creases from sheet metal, or as a clamp. The device’s spring-return jaws are made of highstrength alloy steel. It can be dead-ended at 4" spread under full load. Ideally suited to work with No. 4012 hand pump (not included).
