The solid rubber head of the fiberglass handle rubber mallet delivers a softened strike, protecting parts from damage. Whether it's soft or hardwoods used in construction, cabinetry, and furniture or the chrome, aluminum or magnesium parts on cars, trucks and motorcycles, you can safely apply persuasion without hurting sensitive finishes or surfaces. Made from high-strength, lightweight fiberglass, the virtually unbreakable handle core naturally dampens stinging vibrations.
