ABSTRACT:
A tape measure having sidewalls spaced apart a distance slightly greater than the width of the tape to define a small clearance at opposite edges of the tape with the sidewalls. The sidewalls define midway therebetween a center plane. A peripheral portion of the sidewalls adjacent the peripheral wall of the housing defines guide means adjacent the tape-passing opening for causing the centerline of the tape, as it is passed through the opening, to be accurately at the center plane, thereby effectively minimizing edge wear of the tape in the use of the tape measure.
