Product description
The OX Pro Giant Chalk Reel is built for the demands of big layout jobs. With 45 metres (150 feet) of line capacity and a 4:1 gear ratio for rapid rewind, it keeps you moving on site without interruption. The extra bold line leaves a thick, clearly visible chalk mark on virtually any surface — concrete, timber, brick, drywall and slabs — so you can lay out accurate reference lines even in low-light or dusty conditions. Built with a tough ABS body that can take daily site punishment, and featuring a wide-mouth chalk fill port for fast, mess-free refills, the OX Pro Giant Chalk Reel is the professional's choice for flooring, roofing, decking and general construction layout work.

Ox pro line
Reviewed in the United Kingdom on 18 June 2026I had a Stanley large line for about 8 years, but the gearing gave up, I am a roofing contractor on a big job and needed a quick replacement so saw this ox one, glad I bought it,,
It's been brilliant I did rough up the line with some sand paper before useing it and it's been faultless, keep them dry and they will last for ages my old one. Did like I said it was 8 years before it packed up so can't complain about that definitely buy another one,,
