The NRS Deluxe Kayak Car Rack Kit is a simple, effective system for transporting your boat to and from the water. The non-skid foam blocks protect your kayak and vehicle roof. You can be rigged and ready to go in a snap. Durable minicell foam cushions your boat and protects your vehicle. Your boat secures to the foam blocks with 9-foot padded straps. You can then pop them on factory rack load bars or set the blocks directly on the vehicle roof. A 15-foot padded strap provides secure center tie down support.
