Need to replace the carbon brushes in your ELU MBH90 sander? This set has you covered. You get TWO carbon brushes, each measuring 6.4mm x 10mm x 17.5mm (that's about 2.5 x 3.9 x 6.9 inches). They come with cables, connectors, and springs - everything you need for installation. It's always a good idea to replace both brushes at the same time for even wear. These brushes are designed to last longer than the original ones, and when they wear out, your sander should automatically stop to prevent damage to the tool. The best part? The package is small enough to fit through your letterbox, so you don't have to wait around for delivery. Buildalot has around 50,000 different carbon brushes in stock, so they know their stuff. If you're not sure if these are right for your tool, just check the dimensions and compare them to your old brushes. Customer service is available if you have questions. Keep your sander running smoothly with these quality replacement parts!
