Use a professional glazier
Never try to cut tempered or double-glazed glass yourself. A glazier must normally manufacture a suitable new pane with the opening prepared.
Required circular opening
| Diameter | Result |
|---|---|
| Below Ø 212 mm | Too small |
| Ø 212–215 mm | Flappie fits directly |
| Above Ø 215 mm to Ø 260 mm | Use a mounting adapter |
| Above Ø 260 mm | Too large for this setup |
Floor clearance
Leave at least 19 mm between the bottom of the circular opening and the floor or frame below it.
Before ordering glass
- Show the glazier the required dimensions.
- Confirm the full glass thickness.
- Check whether a mounting adapter is required.
- If the full installation is thick, check tunnel extensions.
Replacing another glass cat flap
Measure the existing circular hole and compare it with Replace an existing cat flap.
