Abstract
An overhead door movement blocking system for selectively blocking opening of an overhead door with a device that is easily and quickly removable and transferred to other overhead doors. The overhead door movement blocking system includes a block device for positioning in the channel of the guide track of an overhead door structure to obstruct movement of the guide roller of an overhead door in the channel past the block device. The block device has inner and outer faces, and an aperture is formed in the block device for aligning with a hole in the base wall of the guide track when the block device is positioned in the channel of the guide track. The aperture extends between the inner and outer faces. The block device has opposite first and second ends, with the first end being positionable adjacent to the guide roller of the overhead door. The first end has a concave face for positioning adjacent to and abutting the guide roller. The block device has a pair of opposite sides extending between the first and second ends for each being positioned adjacent to one of the side walls of the guide track. Optionally, the system may include a padlock having a shackle portion and a case portion, with the shackle portion being removably mountable in the aperture of the block device for positioning through the hole of the guide track to secure the block device in the channel to block movement of the guide roller in the channel past the block device.
