Contractor chalk reel designed for long, visible lines on large building and landscaping jobs. The OX Tools Contractor Chalk Reel pairs an extra-bold 1.75mm line with a large-capacity case to keep teams moving, but does it stand up to heavy daily use?

⚡ At a Glance
  • Marking Precision: Extra-bold 1.75mm cotton-nylon line for clear, high-visibility chalk marks
  • Best for: Builders, landscapers, tilers and serious DIYers needing long layout runs
  • Not ideal for: Fine interior lining where a very thin line is required

30m of extra-bold line sits in a robust ABS plastic case with a 1:1 gear ratio. Hook storage, a pointed tip and a transparent window make site layout more efficient.


Highly visible long runs – thanks to 1.75mm extra-bold cotton-nylon line

A 1.75mm twisted cotton core, reinforced with nylon, forms a thicker strand that retains and transfers more chalk to the surface. The 30m length supports extended runs without frequent re-anchoring.

Clear, easy-to-see chalk lines shorten layout time and reduce measuring errors on large surfaces.

Work longer between refills – with large-capacity ABS case

High-capacity ABS housing stores more chalk and resists impact common on busy sites, while the 1:1 gear ratio ensures steady, predictable feed and retrieval.

Fewer interruptions for refilling keep marking tasks moving and reduce downtime during busy shifts.

Accurate corner marking and monitoring – with pointed tip and transparent window

A pointed tip allows precise anchoring in tight corners, while the transparent window gives a quick view of chalk levels. Built-in hook storage keeps the hook secure when not in use.

Quicker corner anchors and clear visibility of chalk levels prevent unexpected run-outs and maintain layout consistency.
