Choose the right installer for the material
A wooden or suitable PVC door can often be prepared by an experienced DIY installer. For a wall, metal door, insulated door or any uncertainty, use a professional.
Required rectangular opening
| Opening | Result |
|---|---|
| 166 × 170 mm | Recommended for a new opening |
| Existing opening up to 175 × 210 mm | Can fit without an adapter |
| Wider than 175 mm or higher than 210 mm | The opening must be reduced professionally |
Clearance
- Leave at least 27 mm below the rectangular opening.
- Keep the opening at least 30 mm from a door or wall edge.
Compatible materials
- Wood: normally the simplest material to cut.
- PVC: check for reinforcement or cables inside the panel.
- Wall: use suitable tools and fixings for the construction; check for pipes, cables, insulation and load-bearing parts.
Door or wall thickness
The standard frame supports up to 36 mm. For anything thicker, see Tunnel extensions: when and how many.
Before cutting
- Confirm all measurements.
- Check that the power cable can reach an indoor outlet.
- Check whether you need permission from a landlord or building manager.
- Complete the temporary Flappie function test before permanent installation.
