The white Transcat is the same four-way locking mechanism as the clear model in a white frame with a 140mm flap. Two reasons to pick it: the narrower flap suits a small or young cat, and a white frame disappears into a painted door or a white-framed window where a clear one does not.
Four-way locking means in only, out only, both ways, or shut. That is the difference between a pet door you can manage and one that lets anything through at 3am.
140mm is genuinely narrow. Measure across your cat's shoulders while it is standing - if it is close, go to the 180mm clear model rather than hoping.
