BLADES Keson fiberglass reinforced tapes are designed to withstand more wear and tear than any other type of fiberglass measuring tape. They contain 40,000 fiberglass strands for greater tensile strength and superior accuracy when tension is applied. Two coats of PVC protect the tapes from breaking, and a blade shield adds strength to the attachment (the point at which most fiberglass tapes break). These tapes have proven dielectric strength of 200,000 V/M to assure your safety from electrical hazards. FIBER COUNT & TAPE WEIGHT The weight of a tape is a factor to consider if you do a great deal of measuring. With our heavy-duty fiberglass tapes, we pack the strongest possible fibers — and the greatest number — into the thinnest possible tapes to keep the weights down while keeping the blades strong. ELONGATION Tapes elongate (stretch) when excessive pulling force is applied. Keson heavy-duty fiberglass always returns to its proper length after the pulling stops. The reason is our high fiberglass strand count. To keep your fiberglass measurements as accurate as possible, don’t pull too hard when making your measurements. HOUSINGS We have designed a variety of housing types for our customers: Freewheeling Long Tape (FLT), 3X High-Speed Rewind (OTRS) and Standard 1X Rewind (OTR). Double riveted or screwed cases, metal reinforced handles and shovel-style, rubber grips are standard on all of our offerings. PRODUCT SELECTION Keson offers the widest product selection of fiberglass blades. Units, attachments and zero points vary because of the precise needs of our many customers.
