The present invention is a door drop stop system designed to require a minimal amount of time and modification to install in an existing door system. It is effective with all overhead doors which employ a central axle; such overhead doors are in widespread use in residential, commercial, and vehicular applications. In addition, other configurations of the door drop stop system are effective with slab doors, bifold doors, and rollup doors. The present invention will reduce or eliminate property damage and personal injury resulting from a failure of a component of the door or its counterbalance system.
