Professional Aluminum Sanding Board File (70 mm x 400 mm) is a premium bodyshop block-sanding tool engineered for ultra-precise panel flattening, body filler shaping, and primer surfacer sanding. Built with a lightweight yet rigid aluminum sole plate, this sanding board eliminates flex to guarantee a perfectly flat reference surface. It features a versatile dual abrasive attachment system – integrating a high-tack Hook & Loop (Velcro) face alongside heavy-duty end clamps, allowing technicians to use both velcro-backed abrasive strips and plain paper/cloth rolls.
Its 400 mm working length combined with an ergonomic two-handed grip design makes it essential for eliminating surface ripples, ridges, and waves across larger vehicle panels.
