The Marshalltown M634 Mason's Line Winder can be used to create straight lines and a level surface when laying out posts, patios, footings and more. It has been heat set for increased stability and remains unaffected when in contact with mortar, oil, mildew or water. Its orange colour makes it extremely visible on-site and the plastic winder keeps it intact for safe and neat storage.

Complete with 76.2m (250ft) of orange mason's line.
