Marshalltown designed the Rapid Rasp to be a low-cost tool for shaving foam insulation and EIFS (Exterior Insulation Finishing System) to size.
Made in the USA, the flat stainless steel blade won’t round over the edges of the foam, and the aggressive pierced teeth are patterned not to leave tracks behind in the insulation. The Rapid Rasp also features Marshalltown’s ergonomic Durasoft handle.
They sell the Rapid Rasp in four sizes: 14″x2″, 14″x4″, 14″x6″, and 14″x8″. Depending on which size you choose you’ll pay anywhere from $31 to $42.
