RUPES LH19E 6.5" Backing Plate

LH19E 6.5" Backing Plate for Full-Panel Correction

The RUPES LH19E 6.5" backing plate (part 982.650) is the large-format plate RUPES makes for the LH19E rotary polisher sold in North America. The LH19E/US comes with a 5-inch plate; this 165mm plate threads onto the same female 5/8" connection when the work moves to hoods, roofs, doors, and quarter panels. It carries 180mm rotary pads, the size SNS stocks RUPES's coarse and fine rotary foams in, and a 180mm face covers 44% more paint per pass than the 150mm pads that ride on the 5-inch plate. Body shops and dealership detail departments fit it for full-vehicle cutting and polishing, where fewer passes per panel adds up across a whole car.

Units sold overseas run an M14 spindle and won't accept this plate, but on a North American LH19E it's a direct swap: with the machine stopped and unplugged, lock the spindle, unscrew the 5-inch plate, and spin this one on. Hang on to the 5-inch RUPES LH19E plate for spot repairs and tight panels. Brushes, switches, handles, and every other replacement for the machine sit with the RUPES LH19E replacement parts.

What Makes it Great:

📐 Sized for 180mm Pads: A 180mm pad overhangs the 165mm plate by 7.5mm all the way around, enough lip to roll over body lines while the plate's edge stays off the paint.

🚗 More Paint per Pass: Moving from 150mm to 180mm pads adds 44% more contact area, so a hood or roof takes fewer section passes to cut and refine.

🔩 Swaps With the Stock Plate: The female 5/8" thread matches the factory 5-inch plate on the LH19E/US, so going between spot work and full panels needs no adapter.

⚡ 4,000 RPM Limit: RUPES prints a 4,000 RPM maximum on the back, more than double the LH19E's top speed.

Frequently Asked Questions

What size pad goes on a 6.5 inch backing plate?

A 180mm pad, which SNS lists as the 6-inch size in RUPES's rotary pad lines. It leaves a 7.5mm lip past the plate on every side, so the pad face does the work and the plate never touches the panel.

When should I switch the LH19E from the 5 inch to the 6.5 inch plate?

When the job moves from spots to whole panels. The 6.5" plate with 180mm pads finishes hoods, roofs, and doors in fewer passes. Its pad edge also travels 20% faster than a 150mm pad's at any given speed, so watch panel temperature and ease the speed down if the paint gets hot.

Will the LH19E 6.5 inch backing plate fit other rotary polishers?

It threads onto a male 5/8" spindle, and RUPES builds it for the LH19E. On another rotary, confirm a 5/8" spindle first and keep the machine under the plate's 4,000 RPM limit. Rotaries with an M14 spindle need a different plate.
