5"X 5/8 軸心 黑色塑膠背板

Switched from the metal adapter that came with my old sander and this plastic plate is much lighter on the tool. The 5/8 arbor fit perfectly, and the hook-and-loop surface holds the paper tight with no wobble.

This backing plate fits my 5-inch sanding discs perfectly, and the black plastic feels durable enough for regular shop use. It mounted without any wobble on my grinder's 5/8 arbor.

I had been looking for a solid plastic backing plate that wouldn't rust, and this 5-inch one with the 5/8 arbor fits my sander perfectly—no wobble at all.
