SEAL WITH SIDING CHANNEL

A seal useful in sealing slide out rooms may be used singularly or in pairs to straddle a wall through which the opening is located. The seal includes a passageway for containing cabling. The passageway is cooperatively formed by a base, an offsetting member, a movable bulb, and a deformable rib. In use, the movable bulb may be lifted to access the passageway. When closed, the movable lid presses against and deforms the rib to create a substantially water-tight seal around the passageway.
