Rubber Pads for Glass Table

Resting a glass table top directly on a metal frame can cause scratches, noise, and in extreme cases, perhaps even breakage. Inexpensive rubber pads placed in between the frame and the glass table top provide cushioning that reduces friction between the two hard surfaces. They’re cheap and they work.
