Abstract: A tape rule holder of the type used by carpenters, plumbers, electricians and other trades persons formed from two die cut flat pieces of heavy duty, top grain saddle leather. The back piece of the tape rule holder includes belt slots in its upper section. The front piece or pocket-forming member of the tape rule holder is configured in its flat pre-assembly form with peripheral side rivet areas and a bottom rivet area, each defined by a fold line. When the front piece is riveted to the back piece there is formed a tape rule pocket comprising a front wall, side walls and a bottom wall and the side walls present on their inner portion side pocket pressure detent ridges. A leather strap member is affixed to the back piece and has a forwardly arched portion within the tape rule pocket to form an inner back pressure ridge which together with the side detent ridges apply pressure to a tape rule inserted into the leather tape rule holder to grip and maintain the tape rule therein against accidental dislodgement.
