RUPES 125mm (5") Backing Plate for BigFoot LHR15/LHR12E — 5" Hook-and-Loop, M8 Bolt Included

RUPES 125mm random orbital backing plate with 5" hook-and-loop surface and included M8 bolt designed for BigFoot LHR15 and LHR12E polishers.

This single backing plate replaces or upgrades the interface between your RUPES BigFoot random orbital polisher and hook-and-loop polishing pads. Built to the same fitment standard as factory accessories, it attaches with the included M8 bolt and provides a secure, flexible surface for 125mm (5") pads, helping you keep full face contact while working paint, clear coats and composite surfaces.

Which polishers is this backing plate compatible with?

The plate is made specifically for RUPES BigFoot random orbital machines and is a direct fit for LHR15 and LHR12E models. It uses an M8 bolt mounting system and a 125mm diameter to match common 5" pads. Using the correct plate ensures safe operation and consistent pad rotation without slippage.

• Fits RUPES LHR15 and LHR12E random orbital polishers
• M8 bolt included for immediate installation
• Designed for 125mm (5") hook-and-loop pads
• Engineered specifically for RUPES BigFoot tool geometry

How does the hook-and-loop surface affect pad performance?

The hook-and-loop face offers fast pad changes and solid retention during polishing cycles. It balances grip with some flex so pads conform to contours while remaining firmly attached at speed. That stability helps deliver consistent finishing results and reduces pad wobble on flat or curved panels.

• Quick hook-and-loop pad swaps for efficient workflow
• Firm retention minimizes pad slip at operating RPMs
• Slight compliance helps follow bodylines and contours
• Compatible with standard 125mm foam, microfiber, and wool discs

What are the physical specifications and installation steps?

The plate measures 125mm across its hook-and-loop face and uses the included M8 bolt for attachment to matching spindle threads. Installation requires removing the existing backing pad (if present), aligning the threaded insert with the tool spindle, and tightening the M8 bolt to secure the plate. Always follow your tool manual for torque guidance and safety procedures.

• Diameter: 125 mm (5") face for pads
• Mount: M8 bolt included for direct fit
• Single backing plate — sold individually
• Intended for use on RUPES BigFoot LHR15 and LHR12E polishers

Will this backing plate change how the polisher feels or performs?

Using a RUPES-designed backing plate maintains the intended balance and ergonomics of the BigFoot polishers. The plate's materials and thickness are selected to preserve natural tool rotation and responsiveness. While pad choice still affects cut and finish, the right backing plate ensures predictable pad behavior and efficient power transfer.

• Maintains factory handling characteristics of BigFoot tools
• Preserves pad centering for even abrasion and finishing
• Reduces risk of premature pad wear due to misfit components
• Optimizes contact for consistent polishing results

Who is this for: Detailers, body shop technicians, and automotive enthusiasts using RUPES BigFoot LHR15 or LHR12E random orbital polishers who need a reliable 125mm hook-and-loop interface. It’s ideal for anyone replacing a worn plate, switching pad sizes, or ensuring genuine RUPES fitment and performance for consistent finishing work.
