Two drinks and dry storage, one footprint. The 2-Cup Holder with Large Dry Box holds two drinks while the box below stores wallets, phones, keys, cameras, and more. It mounts vertically on consoles, coolers, or bait tanks with a single 4.5? SeaSucker vacuum mount — secure, flexible, and ready wherever you need it. Have a YETI Tumbler or similar oversized drink? Pick up a couple of Tumbler Rings — they snap onto your cup inserts for a snug, rattle-free fit.
