Flex 5.5" Backing Pad for XC 3401 VRG Rotary/Orbital Polisher — 5.5in Hook-and-Loop, 10,800 RPM

Flex 5.5-inch backing pad for the XC 3401 VRG is a durable, hook-and-loop attachment that secures polishing pads for safe high-speed finishing up to 10,800 RPM.

Designed and manufactured in Germany, this backing pad provides a stable, smooth surface for foam, wool, or microfiber polishing pads when working on aluminum, fiberglass, and metal. Its black, smooth-textured face and 1/2-inch thickness balance pad support with some give, helping to distribute pressure evenly during both rotary and orbital polishing tasks.

How does this backing pad attach to my polisher?

The Flex backing pad uses a hook-and-loop (Velcro-style) fastening system that quickly secures compatible polishing pads and allows fast pad changes. It fits the Flex XC 3401 VRG model and is suitable for other polishers that accept the same size and attachment style.

• Hook-and-loop surface for secure pad retention
• Compatible with the XC 3401 VRG polisher
• Quick pad swaps reduce downtime on the job
• Works with standard polisher backplate connections

What materials and surfaces can I use it on?

This backing pad is built for work on aluminum, fiberglass, and general metal surfaces when paired with the correct polishing pad and compound. It provides a steady platform that helps ensure even contact and consistent finish across those materials.

• Suitable for aluminum and non-ferrous metals
• Works well on fiberglass bodywork and gelcoat
• Use with foam, wool, or microfiber polishing pads
• Avoid highly abrasive tasks that exceed pad or tool recommendations

What are the size and performance specifications?

The backing pad measures 5.5 inches in working diameter with an outside diameter of 6.25 inches and a half-inch thickness, offering a balance between flexibility and support. It is rated for speeds up to 10,800 RPM, making it capable of handling both rotary and orbital polishing motions within the tool's specified limits.

• Working diameter: 5.5 inches; outside diameter: 6.25 inches
• Thickness: 1/2 inch for balanced support and flex
• Maximum safe speed: 10,800 RPM
• Smooth face texture for even contact with pads

How do I maintain and replace the backing pad?

Care is straightforward: keep the hook-and-loop surface free of compound residue and grit, and inspect for torn or crushed areas that affect pad retention. Replace the backing pad if the hook surface no longer holds pads securely or if the backing shows structural wear.

• Clean with a brush or compressed air after use
• Remove adhesive buildup for best hook engagement
• Check attachment threads or backing plate fit before each job
• Replace when hook surface or core becomes damaged
