One support extends on each side of the seal and each support has a base and cover that together contain a channel. Each channel is formed from a groove in each of the base and cover, each groove having side walls that continuously diverge from one another to an open face of said groove. The channel is of similar size and shape, but slightly smaller than the ridge so that each ridge is held snugly under pressure in each of the channels. The peculiar shape of the channel allows the supports to be bend in a vertical or horizontal plane while maintaining the channel intact.Field of SearchInterfitting parts | |
