The Yakima Blockhead is an instant bike mount that will bolt to any flat surface on pickups, RVs, and boats (mounting hardware not included). The durable and corrosion resistant Blockhead holds one bike, and comes with a beefy 9mm non-locking skewer. Padding protects your truck's finish. **For Locking Blockhead, see YAK0034 – includes SKS cores & keys.
