Abstract: The fence system attaches to an aluminum or steel rectangular base post in concrete or the ground. The inside wall of a fence column slides over the base post. The fence column also has an outside wall around the inside wall. Each of three side of the fence column has an elongated slot, which receives one end of a slat. A bracket may secure the slat to the fence column. The fence system also has a gate of the same style as the rest of the fence. A lockset housing replaces one fence column. It receives slats on one side, and the lockset's latch projects from the other side. A hollow post has a slot facing the latch when the gate is closed. A latch cover is held by the slot, and an extension of the latch cover extends along the lockset housing to block surreptitious opening the gate.
