normally used in conjunction with a gate assembly which is described in more detail with reference to fig7 provided at each end of the panel assembly 10 is a panel end 14 which is constructed of a rigid material to maintain shape even under pressure from a bovine pressing against the span members connecting the panel ends panel assemblies 10 form a substantially planar surface and are therefore easily stackable for transport for a fence which has a run extending beyond the reach of a single panel assembly 10 there is provided a joiner assembly 20 to join two panel assemblies in a straight line run while supporting each panel assembly relative to the ground the joiner assembly is fabricated with a shorter outer support post 18 and a longer inner support post having an inclined panel mount 22 extending therebetween as with corner assemblies ground runner 24 can be prodded at the base of the joiner assembly extending between the lower portion of outer support post 18 and lower portion of inner support post 19 the ground runner creates a stronger joiner assembly joiner assemblies 20 form a substantially planar surface and are therefore easily compactly stackable for transport referring to fig2 a a cross section end view of the area of contact between the panel end and panel mount according to a first configuration of panel ends 14 is shown in this configuration panel end 14 is constructed from square tubing.
