Collection: Foam Blocks

More About Foam Blocks & Rope

Individual foam carrier blocks and rope for car-top boat transport. Whether you need to replace a worn block from your existing kit or build a custom hauling setup, this collection has the components — kayak blocks, canoe blocks, SUP blocks, and polypropylene rope sold individually.

Riverside® foam blocks come in Standard, Deluxe, Universal, Extra Tall, and Extra Wide configurations to match your hull type and crossbar width. Non-skid laminate surfaces grip your boat and your crossbar to prevent shifting at highway speeds. Diamond Braided Polypropylene Rope is UV-resistant, floats, and holds knots well — ideal for bow/stern tie-downs.

These are the replacement parts and individual components that keep your car-top system working — without buying a full kit when you only need one piece.
