Security Kit. As one customers told us, "my bike's worth more than my car so this lock better work!" An exaggeration perhaps, but we understand. The Security Kit consists of two long-shanked padlocks (same keys) and a heavy duty vinyl coated straight steel cable. The first lock goes through a hole in the Receiver Pipe and the Leg of the Rack, locking the Rack to the car. The cable goes through the bike frames and one or both wheels of each Bike. The cable padlocks to both ends of the cable and a hole through the Leg, locking the Bikes to the Rack. The Security Kit is included as part of each complete Bike Rack, and is included in the pricing.
