Mason Line Applications

  • Lay a straight course. There is no room in a bricklaying job for straying off-line. With nylon mason line close at hand, you can get everything lined up perfectly before the bricks start to go down. 
  • Set posts. You can use mason line for other construction projects beyond laying brick. For instance, if you are building a deck and need to set posts perfectly in a row, a sturdy twisted mason line can help you place them in just the right spot. 

Benefits of Mason Line

  • Save time. Any mistakes made along the way while trying to lay bricks will only cost you time and money later in the job. Using mason line right from the start can help you avoid significant headaches later on. 
  • Minimal stretch. Our Made in USA 100% nylon mason line has very little stretch, which is so important when doing masonry work. Get a tight straight line that you can rely on.
  • Bright colors. SEACO offers a selection of bright colors, allowing you to pick one that will stand out on your job site and make the job easier. 
  • Simplify the job. You may find that you need to reach for your level less often while laying bricks when you are using mason line on the job. While it might take some time to set up your line initially, the overall job can be completed faster thanks to limiting your use of the level.
