Our one-size-fits-all roof rack system is designed for extreme versatility and portability. The Monkey Bars are 48" long round aluminum cross bars to which you can attach accessories for activities such as kayaking, skiing, surfing and paddle boarding, biking, or hauling cargo. Powered by 6" SeaSucker vacuum mounts (4 up front and 2 in the rear), the Monkey Bars fit on just about any car with a roof. Have a wide or narrow roof? No worries, the vacuum mounts can be moved to any position on the bar to ensure a perfect fit for any vehicle. Our folding option allows bars to fold down from 48" to 24" for travel and storage.
