MEASURING TAPE 50' OPEN REEL (FT, IN, 1/8). Keson Industries' OTR fiberglass tape measure measures a variety of sizes, such as 15 meters to 100 meters, 50 feet to 300 feet. It also measures various units in feet and tenths, feet and inches, millimeters, centimeters and meters. Its strong handle makes it easy to grip, making it an effective ribbon for quick winding. Its fiberglass blade is coated with double PVC for the best protection of the tape. It also has double throat rollers that guide the blade return and prevent it from twisting. The metal crank gives users years of use and the improved blade shaft reduces breakage as a result of the tape's weight when dropped.
