Assembly & Installation
With a suitable opening, installation usually takes minutes. A glazier handles new openings in glass.
Two Simple Ways
Have a suitable opening? Fit Flappie yourself. For a new opening, the work depends on the door, glass or wall.
Path A
Often takes just minutes with a suitable existing opening.
Path B
Sit back – we'll take care of it.
Measure the opening and check it with our fit checker. If it fits, you can install Flappie yourself.
A suitable opening is cut into wood or plastic. For glass, you need a glazier.
Our fit checker shows you which installation option fits.

Complete Glass Solution
A glazier manufactures a custom-made pane with a cut-out – you don't have to alter your glass yourself.
Your original pane remains. When you move out, you simply swap it back.

Frequently asked questions
Briefly measure your opening. If it fits, you can mount Flappie directly, often in just a few minutes. For round glass openings over 215 up to 260 mm, the adapter fills the gap. New glass openings require a glazier. The 30-second check will tell you what applies to your situation.
No problem. In a wooden or plastic door, the opening is cut to size; you can do this yourself or a Flappie partner can take care of it. For glass, a glazier will make a new pane with a pre-cut opening. For a thick door or a wall, a tunnel extension ensures the correct depth.
Already have a suitable opening? You can usually fit Flappie yourself in a few minutes. Check the dimensions and whether you need accessories first.
No suitable opening yet? The work involved depends on the door, glass or wall. For glass, you need a glazier. Our installation check helps you find the right solution.
No. For installation in a door or wall, you first get a brief OK from the landlord or administration. When you move out, the spot will be professionally restored. For a glass door, we install Flappie into a new, custom-made pane; your original pane remains and is simply reinstalled when you move out. In a condominium, you briefly clarify it with the homeowners' association.
