The YETI® beverage holder mounts to the side of your YETI® Tundra®, roadie or tank and serves as a secure and convenient caddy for your frosty beverage. This heavy-duty, powder-coated stainless steel holder slides securely into the anchor point tie-down slot of your YETI®, but doesn't get in the way of opening your cooler to grab another frosty beverage. Compatible with the Rambler colster, 20 oz Rambler tumbler, 30 oz Rambler tumbler and 18 oz Rambler bottle.
