An adjustable measuring guide attachment for a picture frame mitering apparatus for miter cutting high double and single rabbited molding strips to predetermined lengths for assembly in particular sized picture frames. The attachment includes a graduated measuring strip adhered to and for highlighting the ruled horizontally extending molding strip supporting arm of the mitering apparatus, and a measuring guide having an angularly slidably adjustable rabbit locator and transparent angularly extending measuring locator member thereon which is affixed to the molding strip retaining bar arranged for slidable adjustment on the supporting arm. An elongated rabbited molding strip, having its leading end mitered, is flatly positioned on the supporting arm with one mitered end abutting the rabbit locator. The retaining bar and measuring guide is slidably adjusted on the arm until the transparent locator member indicates that the predetermined cutting measurement has been reached, whereupon the bar and measuring guide are locked thereat to fixedly position the molding strip on the arm. Actuation of the mitering apparatus causes the opposing end of the molding strip to be mitered to produce a strip of the exact length for frame assembly.
