The MARSHALLTOWN Flat Wire Broom are specially designed with durable steel tines to create uniform grooves in concrete roadways, bridges, and ramps for added water drainage and traction. The machined aluminum tubing won?t warp or crack, and its durable steel tines ensure a long-lasting tool for grooving. Choose between a wide range of broom sizes and bristle spacing to suit your needs. Each Broom comes with a threaded handle adapter already installed. This adapter can also be removed and replaced with a clevis end handle should it suit your preference. Our Flat Wire Brooms are Made in the USA with Global Materials.
