An agricultural baler includes a baling chamber configured to receive a compressible material. The baler includes a plunger proximate a first end of the baling chamber and configured to move within the baling chamber to compress the compressible material into a bale. The baler also includes a rear door assembly having one or more rails positioned at a second end of the baling chamber, opposite the first end. The rear door assembly has a rear door with parallel tracks configured to receive and to guide a strap around the second end of the baling chamber to facilitate surrounding the bale with the strap. The rear door is slidingly coupled to the one or more rails and is configured to move along the one or more rails between a closed position and an open position.
