The FAST RACK , 10 TON , was built as a result of the cheap imports. As a customer you cannot see all the problems of the imports like us. We took all the extra bells and whistles out of our famous Production Rack. Towers are built from smaller round material with a double tubing base to support the sliding nuts under the towers. Two long acme threaded bolts must be used to secure the towers when making a pull. The pinchweld bases and adjustable stems are made from smaller material.
