Automatic apparatus for attaching together individual doorstops and doorjambs in relative registered, longitudinal alignment includes hoppers for containing vertical stacks of the stops and jambs, a transport mechanism that reciprocally withdraws individual ones of the stops and jambs from the vertical stacks and transports the withdrawn stop and jamb to a work station, a registering device for positioning the distal ends of the jamb and stop in relative, adjacent registration, clamp apparatus located at the work station that receives, clamps and longitudinally aligns the stop to the jamb, and a number of linearly aligned air nailers overlying and, in effect, defining the work station for dispensing nails used to attach the stop to the jamb while held by the clamp apparatus.
