Flappie mounting adapter: For round glass openings
The Flappie mounting adapter is the perfect accessory for round glass openings over 215 up to 260 mm in diameter. It bridges the size difference and enables a secure, precise installation.
Round glass opening over 215 up to 260 mm? No problem. The Mounting Adapter bridges the gap and gives you a clean, secure installation.
Good to know: One Flappie needs just one adapter set.
Each set already includes one inner part and one outer part. Together they form one single product, so there's no need to order twice.
You'll need the adapter if:
Our mounting adapter was designed exclusively for the Flappie cat flap. It fits seamlessly into the design of Flappie and ensures optimal functionality. Please note: Mounting adapters from other manufacturers are not compatible with Flappie.
The Flappie mounting adapter fills the gap around round glass openings over 215 up to 260 mm in diameter.
