We broke it down into two segments to block our 28 lb. puppy from two ~7~9 ft. Christmas trees.   Worked pretty well.   We had to push the trees up against the wall this year but it worked.     The gates are pretty stable so we did not have to worry about him tipping them over.    They also worked just fine as a stand alone, i.e. did not need additional support to keep them standing in position.
