Long tape measure for construction layout
The Keson Industries OTR-18M-50 provides a 50 ft and 15 m blade for extended site measurements. Its fiberglass blade resists stretching and conducts no electricity near live circuits. Double throat rollers reduce grit buildup during rewind. The folding hook anchors on edges or studs for one-person operation.
Consistent accuracy over repeated pulls
Fiberglass construction prevents the permanent elongation common in cloth tapes after sustained tension. The clear coating protects printed graduations from abrasion when dragging across rough surfaces. Manual rewind eliminates spring fatigue that causes retraction failure in cased models. Yellow and white blade faces maintain legibility in bright sunlight.
Simple deployment with open-case handling
No lock mechanism means the blade stays extended only while held taut by the user. The ABS plastic case lacks a belt clip so the tool must be carried by hand or stored in a pouch. Folding hook snags less on debris but requires deliberate unfolding before each use. Stud markings assist framing layout without additional tools.

Questions about this item
How much force is needed to manually rewind the 50 ft fiberglass blade after a full day of use?
The open reel uses double throat rollers so the 15 m blade spools back smoothly by hand without a spring mechanism.
Does the 1/2 in wide blade require a specific hook slot or fastener to anchor the zero point?
The folding hook end lets you catch edges, nails or studs directly; no extra hardware is needed.
Will the orange ABS case and yellow-white graduations stay readable if I keep using my older steel tape for reference?
Yes, the clear coated fiberglass blade resists fading and the SAE/metric markings (1/8 in, 2 mm) remain visible alongside any steel tape.
