Keson OTR-1810-50 Long Tape Measure

The Keson OTR-1810-50 is a 50 ft long tape measure built for surveyors, landscapers and construction crews who need to span large distances. Its 1/2 in fiberglass blade resists tearing and stretching across repeated outdoor use.

50 ft blade with SAE and Engineers graduations

The blade reaches 50 ft and carries 1/8 in and 1/10, 1/100 ft graduations for SAE and Engineers measurement types. Precision drops off beyond the full 50 ft extension where the hook end cannot anchor securely.

Manual rewind ABS case with double throat rollers

The ABS housing protects the blade and fits a tool belt or survey vest pocket. Double throat rollers let the blade feed smoothly in tight trenches without snagging, while the manual rewind keeps the mechanism simple and field-repairable.

Questions about this item

Will the 1/2 in blade fit alongside the older 1/4 in tape I keep in my belt pouch?

The 1/2 in blade is wider than a 1/4 in tape, so it needs a larger pouch slot or a separate hook on the belt.

How can I confirm the double throat rollers are feeding the fiberglass blade smoothly after first use?

Extend the full 50 ft, watch the blade run through both rollers without snagging, then rewind — it should return evenly with no kinks.

Does the box include a belt clip or lanyard, or must I buy one separately?

The supplied ABS case has a built-in belt clip; no extra clip or lanyard is included.
