Abstract: An improved adjustable gate structure which is suitable for a fence with an opening therein which is too wide or narrow for a conventional gate, the gate's horizontal width can be increased or reduced by simple mechanical adjustments. The preferred embodiment of this gate consists of a main frame with a plurality of long horizontal panels of equal length affixed parallelographically to a vertical panel approximately 5′ in height and an extension frame with the same plurality of short horizontal panels of equal length also affixed to a panel approximately 5′ tall. All of the panels are spaced equally in relation to the ground. Apertures are punched or drilled equidistantly in the short panels and the distal ends of the long panels. The method to join the two frames at a pre-determined width is to interpose the short panels upon the distal ends of the long panels, thereby aligning the apertures with one or two apertures being secured on every set of panels with fasteners.
