The hook & loop attachment method of this 125mm (5”) Backing Plate means that any hook & loop enabled polishing pad can be used with this backing plate, giving you a greater level of freedom in selecting your accessories. Our 125mm (5”) Backing Plate is designed for use with our M18 FUEL™ 21mm Random Orbital Polisher. The durable rubber design aids in the dispersion of heat in applications which prolongs the life of the backing plate itself, saving users both time and money. With a smaller diameter, compared to the original pad included, users can access smaller spaces to thoroughly polish entire surfaces with ease.
