A compact, lightweight and small removable device enhances the operation and utility of a
tape measure when measuring metallic or nonmetallic structures. The device comprises a flat base, a small, powerful
rare earth magnet secured to one side of the base, and a spring clip that extends from a bottom edge of the base and up its other side and includes a curved surface normally contacting the base to provide a pocket having an entrance slot for
insertion of the zero hook. The zero hook is clamped between the base and the spring clip when inserted through the entry slot into the pocket. The small powerful
magnet enables use with metallic surfaces behind wallboard, and above, below and beside the zero hook. A plurality of friction enhancing tangs extend from the spring clip in a direction opposite the
magnet for gripping nonmetallic surfaces. The device can also be used to retrieve remote
metal tools and other objects. The device is selectively and easily manually attached to and removed from the zero hook, and easily stored in a worker's pocket.
