Is there any gate that a 32" can get through that the 34Z could not? What are ALL the standard gate widths/openings? Anybody know all of them? The reason I ask is that on the most narrow gate I pass through, my 32" has about 2 inches to spare. It maybe even 2 1/2 inches. Just looking at the alternatives in case my 32" dies on me. Any info is appreciated.
