لوحة دعم بلاستيكية سوداء مقاس 7 بوصات بفتحة 5/8 (صنعت في سويسرا)

I was pleasantly surprised by how rigid this backing plate feels compared to cheaper options; the Swiss-made construction really seems to hold up under pressure. The 5/8-11 arbor threaded onto my grinder spindle perfectly, and the retainer nut hasn't loosened once during use.

The 5/8-11 arbor fit my grinder without any wobble, and the Swiss-made plastic feels dense and solid, not brittle. Only gripe is the black finish scuffs easily, but that’s cosmetic. Works fine for backing up sanding discs on my setup.

The retainer nut threads on smoothly and holds firm—no wobble at all during use. It feels sturdier than the cheaper plastic plates I've tried before, a solid upgrade for the price.
