Built around a unique design that uses vacuum cups and interchangeable mounts to easily switch between carrying bikes or skis, Seattle’s Stag Rack has created a vacuum pod roof rack that works with any vehicle. No roof rails needed. Each of the system’s four feet secure in place via two 6” vacuum cups. Built-in pumps seal them in place, and a pressure indicator lets you know when that seal is good to go, with 200+ lbs of strength. The entire mounting process takes about two minutes.
