Long fiberglass tape for site layout
The Keson OTR-18M-300 is a 300 ft and 90 m open-reel tape built for outdoor measuring tasks. Its yellow and white fiberglass blade carries SAE and metric graduations down to 1/8 in and 2 mm. Stud markings help with framing layout. The orange ABS case fits a hand but has no belt clip.
Open case with manual rewind and no lock
Pull the blade out by the folding hook and crank the handle to rewind it; there is no spring return and no blade lock. Double throat rollers guide the tape back into the case to reduce binding. Dirt can still enter the open housing, so wipe the blade before reeling it in to avoid grit jamming the rollers.
300 ft reach for long runs and rough ground
The 1/2 in wide fiberglass blade spans foundations, fencing and utility trenches without stretching like cloth tapes. It handles the full 300 ft in one pull, but the manual rewind becomes slow at maximum length. The tape has no standout rating, so it cannot stay rigid horizontally without support.
