Marshalltown 833D heavy-duty zinc concrete groover with 6 x 4-3/8 inch blade and DuraSoft handle.
Marshalltown has been manufacturing concrete, masonry, drywall, and tile tools in Marshalltown, Iowa since 1890. Every trowel, float, groover, and edger is American-made with carbon-steel or magnesium blades and the brand’s signature DuraSoft handles that resist solvent and concrete chemistry.
Marshalltown is the dominant brand for concrete pros — used on residential pours, commercial slabs, and tilt-ups across the United States. The tools take a beating and last for years; replacement blades and parts are stocked at the Marshalltown Iowa facility.
Made in the USA. The standard for concrete and masonry trade tools.
