Keson OTR-18-50 50 ft tape measure

This open-reel tape measure provides a 50 ft blade length with a 1/2 in width for extended linear measurements. It is built for surveyors, landscapers and tradespeople who need to span long distances on site. The fiberglass blade resists stretching and non-conductive hazards while the orange ABS case protects the reel during transport. Graduations are marked in 1/8 in increments using SAE units.

Open reel design with manual rewind

The open case uses double throat rollers to guide the blade smoothly during extension and manual rewind. A folding hook tip secures the zero point on edges or stakes without a belt clip or lock mechanism. White blade coating improves readability in bright conditions and the clear coating protects the printed graduations. Stud markings assist with framing layout tasks directly on the tape.

50 ft capacity for long-run layout

The 50 ft blade comfortably handles property lines, fence runs and foundation checks where shorter tapes fall short. Fiberglass construction prevents kinks that steel tapes develop over repeated outdoor use. Manual rewind requires operator effort on very long pulls and the open case offers no spring-assist retraction. Users needing standout rigidity for overhead solo work should note the standout is not rated.

Questions about this item

How far does the 50 ft fiberglass blade extend before the open reel case requires manual rewinding?

The 50 ft blade reaches its full length; the open ABS case has no lock or spring, so you must crank the manual rewind handle to retract it after each measurement.

Does the white fiberglass blade stay cool and quiet when left stretched out in direct sun all day?

Fiberglass does not conduct heat like steel and has no moving parts while extended, so it remains silent and near ambient temperature during prolonged outdoor use.

What mounting point does the folding hook need to catch on for the zero-point graduation to read accurately?

The folding hook grabs edges, nails or studs; the zero-point is set at the hook's inner face, so the catch must sit flush against the workpiece for a true reading.
