The Anchor Lock is built from a 10mm steel wire beaded cable wrapped in neoprene casing, long enough at 8 feet to loop through multiple bikes at once. It's a separate job from the pad's own integrated lock: that cable keeps the Basecamp Pad anchored to the tailgate, while this one keeps the bikes themselves secured to the pad. What Our Gearhead(R) Experts Are Saying:"I've run this cable through three bikes at a trailhead and gone for a hike without thinking twice about the truck. The neoprene casing keeps it from marking up frames, so it's doing security work without leaving scuffs behind."
