It is important that the person who purchases the EZ-Puller be familiar with the machine the tool will be used in. If the machine has a wedge lock mounting system for holding square tooling, the body of the bar puller may cover one of the tightening bolts. If this is the case, the tool will need to be moved out from the center of the turret to access the socket of the tightening bolt that is covered by the body of the tool. Many times, this procedure will put the tool at a distance from the center of the turret that will make it interfere with the way covers of the machine. If this is the case, the better mounting option would be the 1.000″ round mounting, either standard or low profile. With this option, the tool will be held in an I.D. tool holder. Please look at the diagrams of mounting options before ordering.
