Abstract: The portable tool tray with wind blocker is a portable rectangular frame with a tray screen forming its bottom and also including a wind blocker that can be stored inside the tool tray or affixed in an upright position perpendicular to the tray to shield the worker from the wind. The wind blocker is stored inside the tray by being slid along tracks that are cut along the lower portion of the tray frame or being inserted within slots laterally defined within the sidewalls of the tray frame. The tray frame may have a faceplate that is of lesser height than the rest of the tray frame to allow the wind blocker to be slid into the tray frame. The wind blocker is equipped with sliders that allow the wind blocker to be slid along the tracks or into the slots defined within the sidewalls.
