Abstract: A quick latch system for attaching a toolbox to the side panels of a pickup truck. A shaft is attached to a clamp arm, forming a pivot. The shaft is inserted through a hole in the base of the toolbox, and a fastener is attached to the end of the shaft. The shaft is dropped into the box in the side panel of the pickup truck, and the clamp arm is rotated, thereby moving the fastener upwards towards the base of the toolbox. When the clamp arm is snug with the base of the toolbox, the clamp arm is pivoted to a horizontal position, clamping the toolbox to the side panel.
