发明名称 FENCE
摘要 A fence with wooden panels having their upper and lower edges disposed in slotted rails supported between pairs of steel posts. The rails can be sections of channel or open seam pipe. The panels are held in place in the fence without nails, screws, bolts or other fasteners, and can be spaced apart like pickets, or have their side edges in contact for denying visual, as well as physical, access to the fenced-in area.
