Deluxe Aluminium - How to differentiate between the Deluxe Aluminium (V1) and (V2) Pet Door

Deluxe Aluminium Pet Door – Identifying Your Version 

There are two versions of the Deluxe Aluminium Pet Door currently in circulation. While the SKU has not changed, you can identify which version you have by looking at the flap holder mechanism: 

Key Design Change: Flap Holder Mechanism

• V1: Features a clamp-style mechanism with two small, discreet screws located on the left and right edges of the flap lip.
  
  
• V2: Upgraded to a screw-in style, using larger bolts that go directly through the flap itself

These differences are the only way to determine which version you own.
