Despite its disarming simplicity, a mason line is one of the most essential tools in masonry. It is used for aligning bricks or blocks and ensuring that the final surfaces and finishes are perfectly leveled. Typically, it is stretched horizontally to provide a guide for the correct construction of the wall. While the procedure is elementary, the step of placing the twine is crucial to get straight, aligned, and leveled constructions. If the line is not perfectly straight and stretched, or if it starts sagging at one point, chances are that your wall will look a bit curved, and you will be forced to do it again.

Line stretchers ensure that the mason line is correctly placed and firmly secured. Typically, these pieces are mounted on key blocks and make the line stay taut. The system of movable bolts and wing nuts allows workers to adjust the alignment if required. Stretchers are made from aluminum and used together with a series of steel twigs keeping the alignment between the key blocks. For an extensive selection of contractor-grade line stretchers and twigs, browse our online catalog. We offer quality products made by reputable companies to deliver efficiency and durability at reasonable costs.
