(1) Genuine Nikon D300 base rubber unit. $12 PP'd and shipped.
These rubber units are the same as the one that comes on the camera and are Nikon OEM spare/replacement parts. I ordered these because they are easily worn with the friction of the thumb/palm and the tripod plate. They are self-adhesive and all you need to do is peel off the old one and put the new one on.
