The Stanley 100-Foot Open Reel Fiberglass Long Tape Rule has a 100-foot blade length and a 1/2-inch blade width. The tape is constructed from an increased number of fiberglass strands, which reduces stretch for better measurement accuracy. Its PVC construction makes the tape easy to wind and clean. The open reel tape rule features easy-to-read, two-sided printing with fractional/decimal formats for the most accurate measurements. Its rubber grip is designed for comfortable use, and its high-visibility color makes it easy to find on the job site.
