The Yakima Locking Blockhead is bomber security. The Locking Blockhead holds one bike, and mounts on pickups, RVs, and boats (mounting hardware not included) . It locks your bike to the mount with SKS cores and keys, which are included. The durable and corrosion resistant Locking Blockhead also comes complete with a beefy 9mm skewer. Padding protects your truck's finish. Non-locking Blockhead also available.
I bought several cargo management and this is the right one.
