A horizontally extendable, two section gate assembly for use in restricting access through a wide opening that is defined by a pair of horizontally spaced and vertically extending walls. One end of the gate mounts hinges that are removably received within hinge brackets mounted on one wall. A swing stop allows the gate to swing in only one direction. The other end of the gate mounts a manual latch mating with a latch bracket mounted on the other wall. Two gate sections each include a horizontal upper support bar. Each upper support bar includes a horizontally extending open face slot that mates with the open face slot in the other support bar. Opposite ends of the two slots include a fixed position and extending slide block. Each slide block is fixed within one slot and is movable in the other slot, to provide low friction relative movement of the two gate sections, and to support the two gate sections in an extended position so that no gate sag is experienced. Opening the two gate sections to the fully extended position is limited by the position of two of a number of U-shaped metal brackets that hold the two gate sections together. Alternatively, the slide blocks are positioned t…
