Mason's Line 500 ft Nylon

This 500 ft nylon mason's line in yellow and black provides a bright, bonded guide for laying brick, block or stone courses. With a maximum tensile strength of 165 lb it resists snapping when pulled tight over long runs. The single-piece spool suits professional masons and DIY builders who need a reliable reference line on site.

Sustained tension on long runs

The bonded nylon construction keeps the line from fraying or stretching excessively when held under load for extended periods. At 165 lb breaking strength it maintains a straight layout across a full 500 ft without frequent re-tensioning. This behaviour reduces the need to stop and adjust the line during a full day of wall building.

Simple spool handling

The line pays out cleanly from the spool and rewinds without tangling if kept under light tension. Weighing .55 lb it adds negligible weight to a tool belt or bucket. The only common issue occurs when the line is stored loose; knots can form that must be picked out before the next use.

Questions about this item

How much does the 500 ft spool weigh when I carry it around the job site all day?

The spool weighs 0.55 lb, making it light enough to keep on a belt or in a tool pouch for extended use.

What do I need to anchor the line so it stays taut while I lay brick?

You will need line blocks, line pins or corner poles to secure each end of the 500 ft nylon line during layout.

Will the 165 lb tensile strength hold up when I pull it tight next to older steel corner poles?

The bonded nylon resists stretching and the 165 lb rating handles normal tension against metal poles without snapping.
