This 5/8-inch Male Backing Plate Extension is a simple yet valuable accessory that extends the reach of your polisher, letting you access recessed areas and tight spots that would otherwise be out of range.

The 5/8-inch male thread is a common polisher fitting, making it a versatile addition to many setups. Sturdy and dependable, it expands the capability of your existing equipment so you can achieve complete, even coverage across the entire vehicle. Pair it with your compatible backing plate, pads, and your favorite RCP compounds and polishes to reach every corner and deliver a consistent, professional-grade finish.
