The setup took a little while to get just right but once they are on, they feel very secure, especially if you use the lock cylinders. Looks clean, locks onto my car's roof and holds whatever I put on them. Another great product from Thule
This surfboard rack has everything you could want. It locks to the bars and locks in your boards for ultimate security. It quickly and easily attaches to any size/shape bars. It holds two surfboards securely and adjusts to fit different size boards. Sure, it's a bit bulkier than some other surfboard racks out there but it's well worth it. Highly recommended!
