could be designed to allow ample space when fully engaged and the trapped air may compress within the gap and not need to escape finally in another embodiment either the peg 30 or receptor 40 element may be designed with vent holes to allow air to escape this improves the assembling process because air trapped in the cavity of the hollow receptor as the peg is forced into it exerts a pressure hindering the mating of the receptor and peg components see fig1 by providing the venting enhancement the finial halves may be assembled using less force and fewer clamping strokes fig1 17 illustrate how the exterior of the finial molds are designed to allow the placement of additional finials via protrusions 110 125 or recessions 75 either on top of or beneath the assembled finial decorative elements some decorative elements may not employ the pressure fitted unisex halves but simply be designed to allow placement upon another finial 39 s protrusion in one embodiment a 4 u2033 finial sized to fit on a standard 4 u2033 fence post would also fit upon a 5 u2033 finial that fits a 5 u2033 fence post and has a 4 u2033 protrusion the dimensions of the base 130 of the finial 35 100 may be varied to fit any fence post the dimensions of other components of the finial may.
