Spinfire Calibration Scale

AUD 50.00 New

Regular Price: $90.00

Special Price $50.00


An essential tool for stringers who care about doing a good job. If you string for clients or friends then you should know that your machine is pulling accurate tensions.

Using this simple tool you can measure (in kilograms or pounds) the tension your stringing machine is actually pulling. The next time you string a racquet at 58 pounds you will know that you are accurately doing so.

To use this tool, you simply place one end of string in a clamp & the other end in the string gripper. If you use flying clamps then you tie one end around the machine. Set your machine to 60 pounds (or anything you like) & then pull the string.

If the scale says you are pulling 60 pounds then your machine is perfectly calibrated. If not, you need to calibrate your machine. If you are technically minded, you can do this yourself, or you can take it to your local pro shop. You should test your machine on varying weights, we recommend 50, 60 & 70 pounds.
