Made of high purity magnesium, quality material that won't rust, extending the life and use of this screed. This masonry tool was built for strength and rigidity, but lightweight enough for the largest of jobs. The 2 ft. screed is easy to move along forms on large slab projects. The 1 in. x 4 in. "easy grip" size is comfortable to hold while hand screeding. Plastic end caps extend the life of the tool by eliminating the opportunity for concrete and other materials to build-up within the screed. Popular for leveling material in concrete paving and landscape work.
