ABSTRACT:
An apparatus that accurately measures rope, wire, tubing and other materials is herein disclosed. A variety of different-sized models would possess different sized openings. One model with a one-inch opening would be used to measure small wire and cable. Another model with approximately a 3-inch opening would be used for larger electrical cables, rope, tubing and the like. An even large model would be available for measuring ductwork, hoses, and other large diameter material. As the material is pulled through the opening, an optical sensor, similar to that used on an optical computer mouse, accurately measures the material to the fraction of an inch. A mechanical sensor, utilizing a guide wheel is also envisioned. The length is displayed on a digital readout on the perimeter of the invention that is provided with a power button, reset button and the like. It is envisioned that various attachments such as a belt loop, a spool attachment and other items to increase the versatility of the invention would also be provided.
