The L-shaped design of the MARSHALLTOWN Power Screed Board makes it an ideal board for wet and form-to-form screeding. The curled edge allows the concrete to roll forward, leveling high spots and filling low spots. This concrete tool features a durable aluminum alloy construction that is engineered to withstand prolonged vibration. Choose from a wide range of sizes. The 16’ option comes with your choice of one- or two-hole mounting, giving you the ability to attach one or two Power Screeds. All Board options fit both our MARSHALLTOWN Shockwave™ and Speed Striker™ and are Made in the USA with Global Materials.
