A plenum for a pneumatic conveyor of the type used for the movement of bottles and the like. The plenum comprises a central housing for receiving pressurized air, a cross block positioned within the central housing and generally spanning across its width, at least two bottle neck supports permitting bottles to be suspended from the plenum, and an air diverter to divert pressurized air from the interior of the central housing to the bottle neck supports to drive bottles along the length of the plenum. The cross block fixes the vertical positioning of the bottle neck supports to maintain the bottle neck supports in a parallel and co-planer configuration thereby helping to maintain the vertical alignment of bottles and the like suspended from the plenum and facilitating in their movement along the length of the plenum. The invention also comprises a cross block for use in a pneumatic conveying system to assist in maintaining the vertical alignment of bottles or the like suspended from and transported along the conveying system.
