Makita CARBON PLATE - 421648-9
424057-1 supersedes older part numbers: 421648-9
Original Makita 424057-1 carbon/graphite plate — a genuine Makita replacement backing plate for belt sanders, made to restore smooth belt support and reduce heat transfer for cleaner, longer-lasting sanding.
Fits common Makita belt-sander frames such as the 9403 / 9403J and M9400 / MT940 / MT941
Key details: graphite/carbon construction, engineered to sit under the sanding belt and protect the platen; approximate part length 170 mm and intended for 100 mm wide sanding belts (standard 610 mm belt loop on these models). Makita parts are made to the same mounting profile as the original unit so installation is straightforward.
Sold as the single replacement plate (part no. 424057-1) for restoring sanding performance on compatible Makita belt sanders.
