Braided Mason Line Replacement Roll Contractor Pack 500 ft - High

Our review of the Braided Mason Line Replacement Roll Contractor Pack finds it a practical choice for masons, landscapers and contractors who need long, highly visible layout line. The pack of six 500 ft rolls of fluorescent orange #18 nylon gives plenty of length for large jobs, and the braided construction delivers noticeably better abrasion resistance than twisted twine. For anyone who relies on a plumb bob or regular layout work, the line's reduced spinning and clear visibility are the single biggest reasons to consider this product.

Key Features

• Fluorescent Orange: The bright color makes layout lines easy to see on most jobsite surfaces, reducing mistakes and rework.
• Braided Construction: Braiding increases wear resistance so the line holds up better under repeated use and abrasive contact.
• #18 Nylon: The nylon material balances flexibility with toughness, making it suitable for masonry and construction layout tasks.
• 165 lb. Breaking Strength: High tensile strength gives confidence when tensioning lines and using a plumb bob without fear of breakage.
• Contractor Pack Quantity: Six 500 ft rolls provide ample length for multiple projects or sharing across crews, limiting the need to restock.

Who It's For

This product is aimed at tradespeople who lay out large areas regularly, including masons, concrete crews, landscapers and general contractors who need a visible, durable string for squaring and alignment. The contractor pack quantity fits busy jobsites where multiple rolls are used each week, or where different crew members need their own roll.

DIY homeowners with only occasional small jobs may find the pack more than they need, both in quantity and total length. If you need specialty colors or a different diameter core, look for single-roll retail options elsewhere.
