Harder than I thought to get in there and show them well, but I hope these help! These are 3 piece snaps at each corner of the carpet. They were purchased from a marine store. Two pieces through the carpet, chrome button (pile side)has a shank that works like a rivet to the snap side on the back of the carpet, and the panel attachment is screwed to the panel! I preferred this way rather than gluing since they can be easily removed for cleaning etc.!
