TOP LINE LADDER-MOUNT BIKE RACK
This bike rack is designed to attach to an existing ladder that has eliptical or flat steps on any recreational vehicle or van. A revolutionary "docking-system" allows the rack to hook on, without the use of tools, in five seconds. Weighting just a little over two pounds, the rack safely holds two bikes, and is made of high strength aluminum alloy. Not for round/square step ladders.
