Use the NRS Universal Foam Canoe Blocks (set of 4) to protect your canoe and the top of your vehicle during transport.
- Durable minicell foam cushions your boat and protects your vehicle.
- The slot in the foam blocks can pop onto the canoe gunwales (two per side). Then the flat non-skid surface is placed directly on the vehicle roof.
- You can also slip the slots in the blocks over factory rack load bars and set the gunwales on the non-skid surface.
- Please note: Tie-down straps are necessary to safely carry a boat on your car.
