Keep your beverage within reach on the boat, at the campsite, or on the river. Mounts to the side of Yeti Tundras, Roadies or Tanks and serves as a secure and convenient caddy. This heavy-duty, powder coated stainless steel holder slides securely into the anchor points but doesn’t get in the way of opening your cooler.
