W. Rose™ Premium Bonded Braided Mason’s line is the highest quality mason’s line on the market. Show your American pride with this tube of 685' of the "All-American" red, white and blue line, which stands out on most jobs. The no sag line is perfect for laying out block and brick. The super strong, super tough is made of braided nylon. The line is then bonded and better knot holding and additional abrasion resistance. The line stands up to the abuse of a job site from trowels striking it. The line is tested to 216 pounds making it 35% stronger than regular mason’s line. Proudly made in the USA.
