2.350" double-knurled standoff and aluminum thumb wheel for Hands Free Adapter
The double-knurled pin is 0.1" longer than the two original contact pins. It must be installed at the top of the SmartCamber tool to keep the tool properly calibrated (it offsets the thickness of the Hands-Free Adapter). The new pin comes with the purchase of Hands-Free Adapter (HFA). Previous HFA buyers (prior to October 2014) can purchase it separately to update their HFA. Works in conjunction with the HFA and SmartCamber products.
