Watch this video explaining how it works:

Manual Crank Conversion

Dropweight conversion


Diablo: The diablo is the round attachment in front of the string gripper which you can wrap string around. It's ideal for multifilament and natural gut strings to reduce crushing the string in the clamp. The height is adjustable for use with different machines. This is now included with the machine as a standard feature.

Foot Pedal: To speed up the stringing process, simply add on the foot pedal allowing you to touch it with your foot to activate the pull mechanism. This keeps your hands free and decreases stringing time. Click here for more information.

Drop Weight Bracket: If you plan to convert a drop weight machine, you will need to add a drop weight bracket. This bracket fits perfectly to Spinfire stringing machines as well as various other brands (hole spacing is 70mm from centres, designed for two M8 x 25mm screws (screws are not included, you should use the original screws that were holding in place the drop weight mechanism)). Some models (other than Spinfire) may require an extra hole to be drilled into this bracket to make it fit or even to widen the existing bracket holes so that the original screws can fit through.

Gamma Adaptor: For Gamma, Klip, iStringer and other similar machines, you may wish to raise the tension head higher. To achieve this, you will need the Gamma Adaptor. Click here for more information.

Gripper Switch Adaptor: This after-market adaptor has been designed to perfectly fit any WISE Tension Head with the red button switch on the back of the gripper. Simply install this adaptor over the top of the red button to improve your stringing experience. Once installed, you can simply pull your string onto the adaptor lever to activate the pull.
