The Wise 2086 Professional Tension Head adapts to all crank and all drop weight machines. In minutes, you can be stringing like the professionals. Imagine the features of the most expensive machines added to your own stringer: electronic speed control, constant pull, linear gripper, pre-stretch, digital readout and much more. String with consistency, accuracy and ease. There is no other machine like it. None.

The Wise 2086 Tension Head delivers accuracy to one tenth of a pound and uses a professional style linear gripper. The machine weighs 12 lbs. and its sturdy aluminium case is anodised gloss black for a chip-free durable finish.

This tension head is designed to convert your existing manual pull machine to a modern constant pull stringing machine. It takes only minutes to simply remove your manual tension head and clamp on this electronic head.

The gripper switch and Diablo are standard and therefore included on the current machines, version 14. Version 14 can pull tension as low as 15 pounds (6.85 kg) to 86 pounds (39 kg) and is suited for stringing tennis, squash, badminton and racquetball racquets. The Diablo is ideal for all strings but most specifically, multifilament and natural gut strings to reduce crushing the string in the clamp. The Diablo also reduces the stress on strings and it's included within the box.

Pre-stretch is built in with the option to set the amount you want, if applicable. At 50 pounds plus 15%, you will see the digital read-out go to 57.5 pounds, pause, then return to the set point. The Wise 2086 also allow calibration with a calibrator.

Just about all crank, basic electronic and drop weight stringing machines are suitable for conversion.

All drop weight stringing machines will require an adaptor plate, sold separately. Drilling may be required on certain drop weight machines. Compatible out of the box with most Pro's Pro crank stringing machines. Some may need the Pro's Pro modified adaptor. The Wise head is also compatible with nearly all drop weight stringing machines with the purchase of the Wise adaptor - no drilling required.
