3/4-inch wide x 3/8-inch high

The miter clamp is cast aluminum and CNC milled for tight tolerances and a precision fit.  It is designed to fit 3/4-inch wide miter slots. If you have a 5/8-inch or metric miter slot, the Hedgehog miter clamp will not fit. However, we do sell a bundled package that includes a Hedgehog and a 5/8-inch miter clamp.
