Carter X. ★★★★★

Finally, a backing plate that doesn't separate from the rubber after a few uses—the aluminum body feels solid and the black rubber face grips my turbo discs without slipping.

Lucy W. ★★★★★

The 5/8-11 thread seated perfectly on my grinder with zero wobble, and the aluminum body feels solid enough for daily use. My turbo discs sit flush against the black rubber face, so I'm getting smooth, consistent contact on every pass.

Ava M. ★★★★★

The rubber face on this backing plate grips the turbo disc really well without any slipping. The aluminum body feels solid and the 5/8-11 thread threaded onto my grinder without issues. Exactly what I needed for sanding curves and corners.
