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!
 
Fitting directly to the Rhino-Rack Vortex crossbar, the S512 is designed for an easy setup whilst turning it into a dual carrier. Fitting kits are also available for the Rhino-Rack Heavy Duty and Euro bars. One can carry up too 4 watercrafts ((2 x S512 and 2 x S512X) are required.
 
Please note: The paddle cradle on the S512 cannot be used while the S512X extension piece is fitted. 
 
Stainless steel hardware is included.
Strong and durable steel coated for protection.
Product comes completely assembled and ready to fit out of the box.
Universal mounting to suit all crossbar shapes is also included (with fitting kits).    
Note - There's also a fitting kit specially designed to fit the Rola* Rack and Rola* Commercial bars.
