لوحة دعم بلاستيكية سوداء 4 بوصات × 3/8-24 بوصة (تشمل صامولة التثبيت)

This 4-inch plate fit perfectly on my Porter Cable sander, and the included retainer nut saved me a trip to the hardware store. The plastic feels sturdy enough for my daily use, and I’ve had no wobble at 10,000 RPM.

Finally, a backing plate that actually stays put—the included retainer nut makes swapping pads so much easier. Fits my buffer perfectly right out of the box.

Swapped out the old worn backing plate on my sander, and this plastic one fit perfectly with the included retainer nut—nice not to hunt for extra hardware. Handles the 20,000 RPM just fine without any wobble.
