ABSTRACT:
A picket fence includes a pair of substantial vertical posts, a top and bottom rail members supported by each of the posts, and pickets attached to the top and bottom rail members. The posts, rails and pickets are all made of the polyvinyl material. The pickets are attached to the rails by cleats engaging keyhole shaped slots in the pickets. In one embodiment of the invention, the keyhole shaped slots extend in opposite directions, so that the rails must be moved relative to the pickets in order to secure the pickets to the rails. Accordingly, the pickets cannot be removed from the rails without first removing the rails from the posts. In another embodiment of the invention, keyhole slots extend in the same direction, and a locking arm extends from the cleats into the narrower portion of the keyhole slot. Accordingly, in order to remove the picket from the rail, both the top and bottom portions of the picket must first be deflected slightly and the picket must then be forced downwardly. In each instance, it is extremely unlikely that the pickets can be removed accidentally, or by children playing around the fence.
