MC5301W-2-Cup Holder – Vertical Mount

if you want to hold a couple of cans or bottles on a vertical surface like the side of your console or bait tank (or, if you want to get creative, on the side of your vehicle when tailgating), this cup holder is what you need. It attaches with a powerful-yet-simple-to-use SeaSucker vacuum mount, which means you can put it where you need it, when you need it.
