Abstract: A door retainer assembly includes a door bracket configured to be mounted to a door of a service body, a pivot base configured to be mounted to a doorframe of the service body, and a check assembly configured to be removably attached to the door bracket via a rod bushing and the pivot base via a pivot mount. The check assembly is configured to selectively hold the door of the service body in an open position. The rod bushing comprises a dual release bushing so that the rod of the check assembly can be independently removed from the rod bushing even when the rod bushing is mounted in the door bracket and so that the rod bushing can be removed from the door bracket with the rod still attached to the rod bushing.
