The Supply88 Sharp Height Gauges help in setting or checking the height of the sharp keys above the naturals. (See Sharp Leveling Tool). Gauges are sold individually, so you can purchase just one, or multiple gauges to create a set with the heights you are most likely to use. The optional steel wire keychain (with threaded closure) will keep multiple gauges together so they can't be misplaced.
Gauges are clearly marked with both the millimeter and inch dimensions, from 12.0 through 13.0 at 0.1mm increments. If you need a gauge with a height that is not listed, simply order the "Custom" height, and send us a message with this form to let us know what custom height(s) you want, and we will create the gauge(s) your request.
