Abstract: A seal for the closure of a gap formed between a support member and adjacent second member. The seal has a polymeric body forming a sealing segment and a base segment. The seal segment has a sealing lip that extends into the gap to slidingly engage the second member. The base segment has a free distal end with one of a compressible portion and an articulating joint. Additionally, a channel is formed in the support member. The channel has a cavity and an opening in communication with the cavity. The cavity width is larger than the opening width so that the one of the compressible portion and the articulating joint portion is collapsible to a first width less than the opening width to permit insertions of the free distal end past the opening and into the cavity and being expandable in the cavity to a second width greater this first width to inhibit removal of the distal end from the cavity.
