  • Patent number: 4091586
    Abstract: A water tight molding for sealing and protecting a joint formed by the intersection of two surfaces. An underlying molding piece spans the joint and is adhesively attached to the two surfaces in a water tight manner. An outer molding piece is held in spaced relation to the underlying piece by spaced apart connecting members. The outer molding piece prevents water from directly acting on the joint. The underlying molding piece directs water draining from one surface away from the joint downwardly to the other surface.
