Kayak Carriers and Paddleboard Carriers that Can Attach to Top Channels of Crossbars

Hi, Can you tell me what kayak racks and what SUP paddle board racks can attach to Thules Evo Wing Bar by using the barsfoot T-slot thats on top of the bar? I couldnt tell from the videos for which kayak or paddle board racks from Thule or I suppose others this kind of T-slot attachment was possible. Thanks
