The Kreg face frame Assembly clamp is just the thing for making sure that the all important FACE side of your joinery is perfectly flat. A 1-3/4" diameter disk is mounted opposite the standard 3/4" locking plier pad. The larger pad spans the joint on the face side, while the smaller pad stays out of the way on the pocket hole side. Max. open 2-1/4", max. reach 3".
