  • Patent number: 4099763
    Abstract: A seal construction including a metallic channel having a base, spaced side walls extending from the base in the same direction, and arms spaced from the base on the side walls and having ends directed toward, but spaced, from each other. A resilient strip is removably captured in the channel and extends therefrom for engagement with an element to be sealed. The channel base may be welded to a metallic element prior to insertion of the resilient strip to obviate the need for aligned openings for securing means such as screws, bolts, or the like and/or bonding agents of dubious reliability in varying environments.
