RUPES Random Orbital Backing Plate 125mm (5") — Hook-and-Loop Face with M8 Bolt for BigFoot LHR15/LHR12E

A precision 125mm (5") random orbital backing plate from RUPES with hook-and-loop attachment and M8 bolt, built for BigFoot LHR15 and LHR12E polishers.

Replace worn pads or customize your polishing setup with this purpose-made backing plate engineered to match RUPES BigFoot random orbital tools. The plate provides a secure hook-and-loop surface that accepts 5" polishing pads, while the included M8 bolt saves you from hunting for fastening hardware. Its construction balances flexibility and support so pads track accurately across paintwork during machine polishing.

What machines is this backing plate compatible with?

This backing plate was designed to pair with RUPES BigFoot random orbital polishers, specifically the LHR15 and LHR12E series. It mounts using the M8 threaded bolt supplied with the plate, ensuring correct fitment and alignment on those models. Avoid using it on non-BigFoot machines unless the tool accepts an M8-backed, Ø125mm plate.

• Direct fit for RUPES LHR15 and LHR12E polishers
• Includes M8 bolt for secure installation
• Intended for BigFoot-series tool dimensions and spindle pitch

How does the hook-and-loop surface improve polishing?

The hook-and-loop (velcro) face lets you swap pads quickly without extra tools, streamlining pad changes between compounding, polishing, and finishing steps. It also keeps pads firmly in place during lateral and orbital motion, reducing slippage that can cause uneven correction. The surface is sized to match 125mm pads so edge sits flush and pads wear evenly.

• Fast pad changes speed up detailing workflows
• Secure attachment reduces pad movement and chatter
• Designed for even pad wear across the 125mm diameter

How durable and supportive is the plate under load?

RUPES manufactures backing plates to withstand the stresses of machine polishing while offering a controlled amount of flex for pad conformability. This plate provides enough stiffness for consistent pressure transfer, yet enough give to follow curved surfaces without digging. Proper use extends pad life and protects the polisher’s drive components.

• Balanced rigidity for consistent cutting and finishing
• Durable construction suited for repeated professional use
• Helps maintain pad life and protects polisher mechanics

What do I need to know about installation and care?

Installation is straightforward: thread the included M8 bolt into the machine’s spindle and tighten to the manufacturer’s torque recommendations. Keep the hook-and-loop surface clean from compound buildup to preserve grip—use compressed air or a pad cleaning brush. Replace the plate if the mounting face shows excessive wear or if hook loops are damaged.

• Comes with M8 bolt; follow RUPES torque guidance when fitting
• Clean velcro regularly to maintain pad retention
• Inspect for wear and replace when hook loops no longer hold pads

Who is this for: Detailers, body shop technicians and car enthusiasts who use RUPES BigFoot LHR15 or LHR12E polishers and want a reliable, quick-change solution for 125mm polishing pads. It’s ideal for anyone replacing a worn plate, standardizing pad size to 5 inches, or simplifying pad swaps during multi-step correction and finishing jobs. Do not use as a universal plate on incompatible polishers—this product is tailored to RUPES BigFoot specifications.
