ABSTRACT:
The invention includes a clasp that can be mounted to the roller track of an overhead door and a shim that can be mounted to the overhead door or the shaft of the roller. The clasp includes a portion for attaching to the roller track and a blocking portion that is secured in proximate location to the inner surface of the overhead door. When the overhead door is in a closed position, the shim and the blocking portion are engaged thereby encouraging the overhead door towards the door frame. Multiple clasp and shim assemblies can be mounted to the overhead door to improve the seal between the overhead door and the door frame.
