This level jack is a solid-steel 24″ threaded rod welded to base plate at a right angle. Allows for individual adjustment of each leg to help create a level working platform. Precision square acme threads and a massive 9.5″ wing-nut provide increased leverage for ease of adjustment under load. Our load capacity comes in around 68,000 to 72,000 lb. compared to most at 39,000 lb. Our level jack is now press stamped for additional strength. The drop forged wing nut is unbreakable. Finally, this product is zinc galvanized for longevity.
