Abstract
Service access to a transport channel is facilitated by providing a corner for receiving a margin or seam of a wall of the transport channel. A bias is exerted on the margin for pushing such margin into the corner and releasably biasing the wall into a position in which it laterally contains the transport channel. The bias is such as to permit manual tilting of the wall away from the transport channel for service access. After termination of such tilting, the bias restores the wall to its normal position at the transport channel.
