Fogmaster 033 MS Type Motor Brush Kit for 120V Motors

Kit contains one conventional brush and one MS [Motor Saver] brush. The MS brush is designed to shut down current flow when worn, preventing commutator dragging and excess wear.

MS brushes are interchangeable with conventional brushes. We recommend them for heavy duty applications that require regular brush changes, or whenever replacing brushes. They are standard on Sentinel II and drum mounted models, and optional for hand held models.
