Richelieu America Ltd. 642331 Twisted Nylon Mason Line 350 Ft

Product Description

The RICHELIEU AMERICA LTD. 642331 is a twisted nylon mason line designed for layout, alignment, and leveling work on construction and masonry jobsites. Wound on a tube for easy dispensing, this 350-foot spool delivers a 7-pound safety work load rating in a bright gold color that provides high visibility against concrete, block, mortar, and soil. The twisted construction resists tangling and holds a taut line under typical field tension. This line is a standard consumable stocked and used by masons, carpenters, general contractors, and tile setters who need a reliable, fast-deploy reference line.

This mason line is suited for residential and light commercial construction applications including bricklaying, block coursing, concrete formwork layout, fence post alignment, and finish grading. The gold color makes it easy to spot against dark substrates. Packaged in a tube format, the spool is self-contained and dispenses cleanly without the line birdnesting or knotting. It is a common jobsite consumable carried in tool bags and stored in site trailers for daily use across multiple trades.

Installation Notes

Mason line is installed by masons, carpenters, and general contractors using line blocks, pins, or stakes to establish a level reference course. Secure both ends firmly before tensioning to maintain accuracy across long runs. Avoid contact with sharp edges or abrasive surfaces that can nick or weaken the line. Replace the line if fraying or visible damage is observed, as a compromised line affects layout accuracy and may exceed the rated work load.
