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.
• Please note: Tie-down straps are necessary to safely carry a boat on your car.
