    Abstract: The “Add-Ezi-Hold” bracket will be used to facilitate handling of garbage cans or similar containers while using a hand truck. Bracket is designed to fit on center support of hand truck and to slip up and down on the support so as to firmly affix a trash can or other container while moving the hand truck. Container is loaded on the hand truck platform and is tipped or balanced to be in direct contact with back support of the hand truck. Once the container is in this position, bracket is slipped downward with the bottom edge of bracket lip slipping over the rim of the container. This permits hand truck and its load to be moved easily with one hand as opposed to the ungainly method of moving the hand truck with one hand while steadying load (container) with the other hand. To remove the container from hand truck, it is only necessary to lift bracket enough to clear container rim.
