Prince 7000 - 4 Point Stringing Machine 

The Prince P7000 Electronic Stringing Machine features a bright, easy-to-read display that includes your pull speed, pre-stretch, pounds or kilogram units, the mounting system break and knot button. A Diablo gripper provides a 2mm increase of the inner circle, creating less pressure especially on multifilament strings. You’ll use new mounting towers that can be adjusted separately with aluminum screws to fix the frame and new 6 and 12 o’clock racquet holders. It even includes a drawer under the Tension Head Unit for the convenient storage of tools.
