Carlson’s extra-wide walk-through gate is the “we live here” barrier: pressure mount for renters, a real door for humans, and a small pet door when cats (or tiny dogs) get VIP hallway privileges.

Measure the opening twice. Carlson’s fit ranges have quirks — some widths need the extension, and some widths simply do not fit. For stairs, follow hardware-mount guidance; gravity is not a roommate you negotiate with.
