Equalizer sheaths are of a unique and patented design that will surround the cutting blade, allowing only the required depth of cutting edge to be visible at the end of the sheath.
Designed for use with the Excalibur Air powered cut out knife, these sheaths prevent damage occurring to dashboards,headlining or other trim close to the cutting area.
