Richelieu America Ltd. 642581 Mason Line Twine 24x185 White

Product Description

The RICHELIEU AMERICA LTD. 642581 is a white twisted nylon mason line twine rated for a 13-pound safety work load. Wound on a tube spool, this line measures 24 gauge and runs 185 feet per tube. Twisted nylon construction resists moisture, abrasion, and UV exposure better than natural fiber alternatives, making it a reliable reference line for layout work in varied jobsite conditions. It is compact and lightweight at approximately 0.22 pounds, easy to carry in a tool pouch or bucket. Trade professionals in masonry, framing, concrete forming, and general construction reach for this type of line daily.

Mason line in this gauge and length is suited for residential and light commercial construction tasks. Common applications include establishing level courses for brick and block laying, setting form lines for concrete flatwork, marking excavation boundaries, and aligning framing layouts. The white color provides high contrast against most substrate surfaces, improving visibility on active job sites. The 185-foot length is sufficient for most standard residential building perimeters without splicing.

Installation Notes

Mason line is installed by masons, carpenters, concrete finishers, and general construction laborers. Secure line ends to stakes, line blocks, or anchor points rated to handle the tension load applied. Avoid overstressing the line beyond its 13-pound safety work load, as nylon will stretch under sustained high tension and may affect layout accuracy. Inspect the line for fraying or kinking before use and replace if integrity is compromised.
