[Wide Application]: Braided Mason Line #18 Nylon Mason Line is a heavy-duty, medium-stretch line made of high-quality nylon. It is suitable for a variety of outdoor and indoor applications including gardening, marking, DIY projects, fishing, boating, masonry, crafts, and more. The braided design ensures durability in demanding conditions. [Quality Material and High Tensile Strength]: Made from high-strength virgin nylon yarn, this string line offers greater strength than polypropylene twine. The diameter is 0.06 in (1.52 mm) with an approximate tensile strength of 160 lbs. Unlike twisted nylon rope, the braided construction prevents unraveling when cut or knotted. [Long Lasting and Resists Abrasion]: Tight braiding enhances strength and durability. This mason line withstands trowel strikes and resists knotting, kinking, and stretching. It is moisture-resistant, oil-resistant, corrosion-resistant, and abrasion-resistant—ideal for long-term use in gardening and construction. [Easy to Use]: Designed for use with string line levels, plumb bobs, surveying equipment, or masonry line holders. Some versions include a handle for comfortable handling and easy spool reloading. [Bright Colors]: Each roll features a highly visible fluorescent color—ideal for landscape marking, property boundary identification, construction layout, and garden support. The orange color provides excellent visibility outdoors.
