Rhino-Rack Folding J-Style Kayak Carrier
The Rhino-Rack Folding J-Style Kayak Carrier (S512) is a secure, space-efficient way to transport your kayak on your vehicle’s roof rack. The J-cradle design supports your kayak while helping leave room for other gear, and the carrier folds down when not in use to reduce wind resistance and improve clearance.
Clearance Note: We are currently sold out of complete carrier kits, but have limited quantities of the Folding J-Style Kayak Carrier Extension (S512X) only available at a clearance price of $46.99 (regular $186.99) while supplies last.
Important: The S512X Extension is not a complete kayak carrier by itself. It is designed to be used with the standard Rhino-Rack Folding J-Style Kayak Carrier (S512). If you already own the S512 carrier and want to carry a second kayak, this is a great opportunity to add the extension at a major discount.
