What is Mason Line?

Also known as “mason’s twine,” mason line is a durable twine used to give masonry workers a quick yet accurate guide when laying bricks or stone. You will find mason line in either twisted or braided styles and several easy-to-spot colors like neon orange, yellow, pink, and more. 

Since our mason line spool lengths range from 250’ up to 1100’ depending on the mason line chosen, you will never have to worry about running out in the middle of a job.

What Makes a Good Mason Line

Whether it is a twisted mason line or a braided mason line, you will get the best results using a line with a tight twist or braid and made from high-quality materials, such as nylon or polyester. These materials make a superior mason line by offering minimal stretch and no distortion when exposed to heavy weight loads or tension. With any one of these mason line products, you will enjoy at least 150 pounds of breaking strength.

For instance, SGT KNOTS Braided Nylon Mason Line and Twisted Nylon Mason Line are composed of 100% nylon for a strong and versatile mason line product that is not only virtually waterproof but resistant to abrasion, sun, oil, chemicals, and weather.

Similarly, the Braided Polyester Mason Line is made from Dacron Polyester, known for its exceptional quality, durability, and resistance to moisture, UV rays, chemicals, oil, and abrasion.

Other Uses for Mason Line

Mason line can be used for projects other than masonry or hardscaping. In fact, it makes an excellent crafting twine for projects in need of a sturdy twine option where cotton or jute just won’t cut it. Twisted mason line makes an excellent fishing line on the fly, and braided polyester mason line is a highly versatile twine option for everything from masonry work to crafting, camping, survival, and any other indoor or outdoor activities you can dream up that could use a heavy-duty twine product.
