Keson 300 ft Fiberglass Tape

The Keson OTR-18-300 is a 300 ft long tape measure with a 1/2 in fiberglass blade. It uses SAE graduation marks spaced every 1/8 in and features a non-magnetic single hook tip. The high-visibility orange ABS plastic case measures 12 in length and includes double throat rollers for smooth operation.

Manual Return and Non-Locking Design

Blade return is manual with no locking mechanism, so the tape must be guided back by hand. The double throat rollers help prevent blade kinking during rewind, which is the most common issue with long fiberglass tapes. Users should keep the blade clean of grit to avoid premature wear on the graduations.

Check Measurement System and Blade Width

This tape provides SAE units only with no metric markings on the blade. Verify that your project requires feet and inches graduated in 1/8 in increments. The 1/2 in blade width suits general long-distance layout but may not fit tight inside corners where narrower blades are preferred.

Questions about this item

How do I verify the 300 ft fiberglass blade measures accurately after unboxing?

Extend the tape fully along a known 300 ft distance and confirm the 1/8 in graduation marks align at each foot increment.

What components arrive with the orange ABS case and what must I source separately?

The case contains the 1/2 in fiberglass blade with non-magnetic hook end and double throat rollers; no batteries or mounting hardware are included.

Which blade length and width combination suits a solo surveyor needing 300 ft reach?

Choose the 300 ft by 1/2 in fiberglass blade; it provides the full SAE range in a single-sided, manual-return format.
