The FLEX 5” Rotary Backing Pad is designed for use with FLEX 24V cordless and 120V corded rotary polishers. The backing pad securely attaches polishing pads with a hook and loop fastener to prevent slippage of the polisher pad during a detail. The durable construction of the backing pad helps dampen vibration and is ideal for use with 5.5-inch to 6-inch polishing pads.
