Made entirely of saltwaterproof marine-grade polymer, this double drink holder will stand up to years of use in the harshest fishing environments. Holder stows two drinks and features an extra storage box for small necessities such as sunscreen, tackle or snacks. Size: 16-3/4" x 5-1/2" x 3".
I shopped around for this item and found this was the best price. It's made of "poly-board" so it's durable and easy to work with. I drilled a couple holes in the bottom and mounted it with stainless steel screws. The accessory box is handy.
