Misplaced your bottom disc flange located at the bottom of your grinder's center shaft? And then frustrated by the difficulty in finding the manufacturer's replacement part… We've heard this frustrating tale many times over! So we designed a simple solution, the Universal Flange. If you ever misplace or lose the original part, at least you know where to easily get a suitable replacement! Will securely hold all your 7/8” (22mm) center hole single accessories on your power tools Cutaway sides make it easy to release a tight flange with an adjustable wrench or pliers Most accessories that are seated on the manufacturers' flange will also be easily seated on our Universal Flange Securely seat single accessories e.g. flap disc sanders, grinding wheels, single chainsaw blades, carbide discs, wire brushes, masonry blades, polishing and buffing wheels Can be used to replace independent removable flanges, either by user's choice or if lost or misplaced (Some manufacturers' have now secured their flange as an integral part of the grinder)
