Marshalltown M631 Mason’s Line 76.2 m (250 ft) Fluorescent Pink

Description:

The Marshalltown M631 is a high-visibility mason’s line designed for brickwork, block-laying, landscaping, concrete layout, and other site layout tasks.

The bright fluorescent-pink colour makes the line easy to see on site, improving accuracy for straight and level reference lines for walls, footings, patios, and landscaping.
