Abstract
The disclosure describes a sealing device for sealing two adjacent wireway sections positioned in an end-to-end relation. Each wireway section has a lower channel portion for receiving cable and a cover movable between an open position for placing cable in the wireway section and a closed position for covering the cable. The sealing device includes a sealing plate, a seal on a lower surface of the sealing plate, and a connector for connecting the sealing plate to the lower channel portion of at least one of the two wireway sections for pivotal movement of the sealing plate between an open position in which the covers of the wireway sections can be lifted, and a closed position in which the sealing plate extends transversely across the wireway sections over the covers with the seal in engagement with the covers. The sealing device also includes a quick-operating fastening device for releasably connecting the sealing plate to the lower channel portion of at least one of the two adjacent wireway sections. The fastening device is operable when the sealing plate is in its closed position to hold the sealing plate in a sealing position in which the seal is in pressure sealing engagement …
