  • Flexible roof end cap
    Patent number: 5605018
    Abstract: A flexible end cap includes at least one flexible membrane, such as a rubber sheet, for covering the end of the roof rib, having a top peripheral portion and a bottom peripheral portion. At least one frame member is attached to at least a portion of the top peripheral portion of the flexible membrane for supporting the membrane in a sealing relationship with the roof rib. At least a portion of the bottom peripheral portion, such as the portion for covering a ridge profile, includes at least two sealing ribs wherein a cross-sectional height of one rib is larger than a cross-sectional height of the other rib. The sealing ribs with the larger cross-sectional height allow the end cap to accommodate varying designs of roof rib profiles formed by adjacent sheets of roof panels.
