Abstract: The present invention provides a system, method and apparatus for assembling a picket fence. The picket fence includes two or more attachment surfaces, one or more rails, one or more single piece fasteners and one or more pickets. The one or more rails extend transversely to and are secured between two of the attachment surfaces. Each rail has one or more through apertures therein centered on a longitudinal axis of each rail. A single piece fastener is substantially disposed within each rail aperture and includes a housing having an aperture extending from a first end to a second end of the housing. The one or more pickets are vertically disposed between the rails and extend through the vertically aligned single piece fastener apertures. The single piece fastener locks into place within the rail aperture and locks the picket into place without any additional parts.
