A crank operated long tape measure includes a reel member and a casing side member having an internal center post with a conical free end. The reel member has a central shaft extending toward the center post for engagement therewith, the central shaft being axially segmented to define a plurality of leg portions. The free ends of the segmented leg portions bear against the conical end of the center post to assure centering of the reel within the casing while simultaneously providing constant frictional engagement between the reel member and the casing for resisting rotary movement of the reel member with respect to the casing. A long tape blade is secured to the reel for storage within the casing. The blade is provided with a laterally weakened break area adjacent its butt end and a replacement tape attaching aperture intermediate the break area and the butt end. Both the break area and the attaching aperture are spaced from the butt end by a distance sufficient to permit full exposure thereof outside the casing without disengagement of the butt end from the reel. |
