  • Boat rub rail
    Patent number: 4292913
    Abstract: A rub rail assembly for a vehicle such as a boat is the subject of the present invention. An extrusion presents a channel that receives a resilient bumper strip. The bumper strip is designed so that deformation of it in an inwardly direction will actually lodge the strip more firmly within the channel. An integral extension of the channel presents a coupling for securing a line to the rail assembly. A second coupling is adapted to be complementally joined with the first coupling for attaching the line.
