Up for sale is a 3 month hold Progression ST II Crank Head Tensioner. Just the tension head not the complete stringing machine. I am upgrading my stringing machine with an electronic tension head and hence the reason for this sale. $185, shipped within CUSA. You can pick it up locally. See Pics here The stringing machine and tensioner has been used solely for my personal use probably seen 8-10 racquets strung at the most. I have got great results using this tensioner and very consistent stringbed stiffness. Have checked the calibration before listing and its dead on accurate. Please see the pictures and feel free to send me any questions. Please check the product manual to make sure it fits your stringing machine.
