These Surfboard Roof Rack Expansion foam blocks are an awesome way to take full advantage of your existing roof rack system by allowing you to add an additional surfboard! The foam blocks provides just the right amount of space and cushion necessary to stack two SUPs on top of each other for transport.
Do you have two surfboards, but only have a way to carry one of them? If so, this convenient foam spacer will allow you carry that extra board. How it works is simple - you place them inbetween the two surfboards you intend to carry, then you strap it all down. No longer do you need to use rolled up towels or any other makeshift spacer! The foam blocks come precut with a special groove in the top that allows you to run a tie down strap through them. This allows you to tie down both the top and bottom board independently if you would like.
To be clear, this is not an entire rack solution but is meant to be an add-on for your existing rack system. Specifically, this foam surfboard expansion block is meant to be used with surf roof racks that use tie down straps. These expansion blocks are not compatible with specialized hard racks like the Thule Surf Taxi or the Inno Locking Rack. This Surfboard Roof Rack Expansion foam blocks are meant for use with soft racks or for people using factory crossbars with rack pads and tie downs.
