Description: Rubber feet raise your PCB or project up off your desk. This helps prevent short circuiting from bits of scrap wire floating about or setting a project down on a conductive surface. They also prevent your enclosure or PCB from sliding around. They can also be used as feet for enclosures. These are self-adhesive and 16.5mm in diameter and about 10mm tall. They taper to roughly 12mm at the top. They come in a set of 4.

I bought them for a project I was putting in a standard project enclosure and they worked perfectly.
I then noticed that my keyboard was sliding all around on my glass desk because the rubber feet had come off. I put two of these on the bottom of the keyboard (I was a little afraid they were too tall) and they worked like a charm to keep it in place.
