Abstract
Abstract A guide strip has a central raised rib or channel-shaped portion and two edge flange portions projecting outwardly from opposite side edges of the rib portion, one of the edge flange portions is flat to provide a clamping surface and the other has an upturned edge for guiding power tools. A splice strip or coupling is provided for joining the ends of two guide strips together to form a longer guide strip. The splice strip has a channel sized to interfit with the rib portion of the guide strips.
