Abstract
A clip-on picket fence cap assembly that can resist detachment of a plastic picket cap member from a plastic picket member when significant pulling force is applied to the cap member. The legs of the cap member upon which the clips are installed are very stiff by virtue of being reinforced by gussets that resist deflection of the legs when inserted in a picket. The assembly includes metal clips having outer surfaces that are convex curvilinear in shape that enhances their strength and resistance to deformation. The outer surface of each clip is preferably provided with at least one outwardly projecting retention means adapted for secure embedment into the inner wall surfaces of a picket member when the cap assembly is inserted therein.
