The Inno IN417 Slide Extension Kit provides an added level of convenience when loading a canoe, kayak, other styles of boats and other heavy objects onto the roof of your vehicle and into position onto a canoe rack, kayak rack or other gear carrier. A set of sliding crossbars supports a 65 inch crossbar that, when extended, will prevent your boat from coming into contact with your vehicle when loading and unloading. When not in use, the extension easily retracts into stored position so that the rear hatch door of your vehicle can be opened without interference. With a 150 lb weight limit, the Inno IN417 Slide Extension Kit can not only help you load a canoe, kayak or other type of boat with greater ease, you can also load lumber, ladders, pipes, your cousin Lenny’s futon frame, etc. For the ultimate set up, use the IN417 Slide Extension Kit in combination with the canoe rack or kayak rack of your choice. Mounts to Inno multi-purpose base rack load bars and Thule square bars only. Not compatible with factory rack crossbars.
