Surveyors tape measure 300 ft

The Keson SR-10-300 is a 300 ft fiberglass tape measure designed for surveyors and engineers who need long-range linear measurements on site. Its white blade carries engineer-scale graduations of 1/10 ft marked on both sides for bidirectional reading.

Durable fiberglass blade with high tension rating

The 1/4 in wide fiberglass blade withstands up to 200 lb of pulling tension without stretching, so the tape stays accurate during solo layout work. Double-sided markings and stud indicators let you identify start and end points quickly in muddy or dusty conditions.

Replaces cloth or steel long tapes for outdoor

This model upgrades from cloth tapes that sag or steel tapes that kink, giving a single tool that resists moisture and holds tension over the full 300 ft. The jump is worth it when daily site work demands a blade that survives repeated 100 kg pulls and stays legible in bright sun.

Questions about this item

What graduations does the 300 ft tape use, and what is the smallest increment shown?

The blade is marked in engineers units with 1/10 ft graduations on both sides so you can read from either edge.

What is the blade width and what clearance does the reel need?

The blade is 1/4 in. wide and the reel measures 9.300 in. by 9.300 in., so allow at least that square footprint for mounting or storage.

How do you wind the fiberglass tape back without kinking it?

Crank the handle steadily while guiding the blade straight onto the reel; letting it snap back or crossing the strands is the step most people get wrong.
