SeaSucker Vertical Mount 2-Cup Holder
SeaSucker's best-selling cup holder attaches to just about any vertical surface on your boat (but it's also great for tailgating too.). Its cup inserts are big enough to hold 2 cans or bottles in foam koozies and the removable cup inserts are dishwasher safe for those times you spill your cola. Made of 3/4-Inch white plastic pre-attached to a 41/2-Inch SeaSucker.
