Richelieu America Ltd. 644021 Nylon Mason Line Twine 100 Ft

Product Description

The RICHELIEU AMERICA LTD. 644021 is a twisted nylon mason line twine rated to a 6-pound safety work load, supplied in a 100-foot tube pack. Twisted nylon construction provides consistent tensile strength, low stretch, and resistance to abrasion, making it suitable for layout and alignment tasks on job sites. The white color offers good visibility against most masonry and concrete surfaces. Tradespeople in masonry, concrete forming, framing, and general construction use this twine to establish level and plumb reference lines during foundation work, block laying, and tile setting.

This mason line is suited for residential and light commercial construction applications where a reliable, lightweight string line is needed for course alignment, grade marking, and layout. The tube packaging keeps the twine organized and dispenses cleanly on the job. The 100-foot length covers typical wall runs and foundation layouts without requiring splices. General contractors, masons, tile setters, and framing crews are the primary installers and users of this product.

Installation Notes

Secure each end of the twine to a stable anchor point such as a line pin, nail, or stake before tensioning. Pull the line taut to eliminate sag before using it as a reference for course alignment or grade. Inspect the twine for fraying or kinking before each use and replace if the line shows signs of wear. No special tools are required, but gloves are recommended when handling under tension.
