Professional concave rubber backer pads introduce innovative curvature technology for superior edge work and contoured surface finishing. Featuring a unique concave design combined with flexible rubber construction, these backer pads revolutionize how professionals approach edge polishing, corner work, and complex surface geometries. The strategic concave profile allows for controlled pressure application on edges while preventing over-polishing of adjacent flat areas. Reinforced with brass components for durability, these backer pads deliver precision performance on the most challenging finishing applications.
