A support post assembly with mounting bracket assembly and hinge plate with defined bend lines and break points are provided to prevent or reduce damage to objects attached to the support post assembly. The hinge plate has an enhanced section having a channel formed transversely thereacross to function as a bend line when the support post assembly is subjected to a predetermined force. A section of reduced or removed material further directs the force to the weakened area to guide the bending, and openings in the bend line guide breaking or tearing of the plate. Damage is limited to the hinge plate, which is easily replaced. A mounting bracket assembly having a two-piece body for connecting or splicing support posts together includes a strap with crosspiece configured to provide a desired bend line or breakpoint.
