Richelieu America Ltd. 642561 Nylon Mason Twine 525 Ft

Product Description

The RICHELIEU AMERICA LTD. 642561 is a twisted nylon mason twine wound on a spool, designed for layout, alignment, and reference-line work on construction and masonry jobsites. The twine is sized at 18 gauge and runs 525 feet per spool, giving crews enough length for large-scale layout without frequent re-spooling. The high-visibility neon lime green color makes the line easy to spot across a footing, slab, or block course. It carries an 8 lb work load rating. Masons, concrete finishers, framers, and general contractors typically keep this twine on hand as a daily-use consumable for establishing grade, plumb, and coursing lines.

This mason twine is suited for residential and light commercial construction tasks where a visible, taut reference line is needed. Common applications include setting batter boards, running course lines for block and brick work, establishing footing layouts, and general site layout. The neon lime green color aids visibility in both indoor and outdoor conditions, including low-contrast backgrounds such as concrete and soil. Each spool provides 525 feet of continuous line, appropriate for long foundation runs or multiple shorter pulls from a single spool.

Key Features

• 525 feet of line per spool — enough for extended layout runs without splicing
• 8 lb work load rating for consistent tension across layout applications
• High-visibility neon lime green color for easy sighting across jobsite distances
• Twisted nylon construction resists abrasion and maintains shape under tension
• Spool packaging keeps line organized and tangle-free on site

Compatibility

Designed as a general-purpose mason twine suitable for standard line-pin, stake, and batter-board setups used in masonry, concrete, and framing layout work.

Installation Notes

This twine is a hand-applied layout tool and requires no power tools or mechanical fasteners for standard use. Secure the line to line pins, nails, or stakes at each anchor point and apply consistent hand tension before fixing. Avoid running the twine over sharp edges that could cut or fray the nylon strands. Keep the spool dry when stored to prevent mildew and maintain line integrity.
