Need to carry more than one kayak or canoe next time you go paddling?
Look no further. Rhino-Rack has designed an extension piece that
attaches to one of our current kayak and canoe carriers (S512) that will
allow you to add an extra watercraft. Have 2x S512 and 2x extension
pieces and if your roof rack cross bar is long enough, you can have up
to 4 kayaks or canoes mounted on your vehicle's roof!
