Richelieu America Ltd. 642341 Twisted Nylon Mason Line 260 Ft

Product Description

The RICHELIEU AMERICA LTD. 642341 is a twisted nylon mason line designed for layout, alignment, and leveling work on construction and masonry jobsites. This 260-foot spool delivers an 8-pound safety work load rating, making it suitable for light-duty string line applications where consistent tension and visibility matter. The white color provides good contrast against most masonry, concrete, and framing surfaces. Packaged in a tube dispenser, the line pays out smoothly without tangling. Licensed tradespeople including masons, carpenters, and general contractors keep this type of line on hand for establishing reference lines during foundation work, block and brick laying, and concrete form setting.

This mason line is suited for residential and light commercial construction tasks where a durable, low-stretch line is needed to hold a straight reference over long spans. It performs in typical outdoor jobsite conditions and is a standard consumable for masonry and rough carpentry work. The tube packaging makes it easy to store and dispense on a busy site without the line unwinding in a tool bag or pouch.

Installation Notes

Secure line ends to line pins, stakes, or corner blocks rated for the intended application before tensioning. Keep the line clear of sharp edges on masonry or formed concrete that could nick or abrade the nylon strands. No special tools are required, but ensure anchor points are stable before using the line as a grade or level reference. Discard and replace the line if kinks, fraying, or visible wear are present.
