I searched for my replacement part number EXACTLY - this door came up. Picture shown has the part number I need EXACTLY, PAC11-11038. Received the flap and low and behold it has no holes for the screws and it's far too short. It's not even the same COLOR. I received part #4-0111-11. Does anything about those two numbers seem similar to anyone out there? They certainly don't to me, except having a few ones in common.
To whoever said they don't know why people are having problems - well obviously Petsafe changed the set up for the flap installation. "Been the same for 10 years", but OBVIOUSLY has NOW changed, dude. The installation of the flap no longer entails screws securing the plastic between two plates, rather the flap's new design fits into a clamp type setup.
It seems to me, when you search for a replacement part and a result comes up that MATCHES the search in EVERY way, you kind of EXPECT to get the part you ordered, not a newer door flap to a newer model with a newer type of installation. Just sayin'...
I would've given it a one star because I should've gotten what I ordered, not just a door someone grabbed off the shelf, but I think the new design is FAR better and wish that it WOULD fit my door. : /
