The apparatus also includes a head cartridge movably supported by the bracket such that the head cartridge is movable between active position and inactive positions. The head cartridge includes a gate movable between a product-blocking position in which a throat defined between the gate and a front end of the hanger prevents any of the plurality of products from passing therethrough, and a product-releasing position in which the throat permits one of the plurality of products to pass therethrough. The apparatus also includes a lock movable between an unlocked position in which the lock permits the head cartridge to move between the active and inactive positions, and a locked position in which the lock prevents the head cartridge from moving between the active and inactive positions.
