Set the door phone into the wall.
Black frame, flush finish.
The AK-R20INWALLK-BLACK is the Akuvox flush-mounting kit for the R20A and R25A. The flush-mounting box sits in the wall cavity; the black decorative panel holds the door phone and frames it at the surface, leaving a slim black border around the station.
Mounting hardware only.
The kit contains everything to flush-mount one R20A or R25A. The door phone itself and the in-wall rain hood are sold separately.
- Flush-mounting box
- Decorative panel / flush-mounting bracket (black)
- 4 × M3×6 crosshead screws
- 2 × M4×15 Torx screws
- 4 × ST4×20 screws and 4 plastic wall anchors
- Torx wrench
- Akuvox R20A, R25A or R20A-2 door phone
- A 180 × 101 × 50 mm wall recess with cable entry
- Optional: R20A / R25A in-wall rain hood (black) for exposed doors
Flush, tidy and harder to tamper with.
A recessed station sits almost level with the wall face, keeps cabling hidden and locks in with Torx screws instead of hanging on a surface bracket.

What you get
Box plus a matching frame.
The flush-mounting box takes the cables and the body of the door phone, with knockouts on every side for conduit. The black decorative panel screws to the station with four M3×6 screws and forms the visible 189 × 120 mm border.
Two M4×15 Torx screws lock the station into the box, so it cannot be lifted off the wall without the Torx wrench.
Fitting
One recess, sized by Akuvox.
Cut a 180 × 101 × 50 mm (H × W × D) recess with the cables inside, fix the box with four ST4×20 screws and anchors, then fill the gap with cement or non-corrosive adhesive.
On an exposed entry, add the R20A / R25A in-wall rain hood — it fits onto the same flush-mounting bracket before the station goes into the box.

How it works
From bare wall to flush door phone.

Fit the frame
Screw the door station to the flush-mounting bracket with the four M3×6 screws and connect the cables through the wiring cover.

Answers
Common questions
Which door phones does it fit?
Akuvox R20A, R25A and R20A-2. All three use the same 145 × 85 mm housing, 180 × 101 × 50 mm cut-out and flush box. It does not fit the taller R20K, R25K or R20B.
What size hole do I need?
180 × 101 × 50 mm (H × W × D), with the cables already inside it or a conduit to it. The box body is 162 × 100 × 50 mm, and the decorative panel covers 189 × 120 mm of wall around the opening.
How high should it go?
Akuvox’s placement drawing puts the camera centre 1500 mm above the ground, with the bottom of the decorative panel at 1375 mm — or 1355 mm when the in-wall rain hood is fitted.
What is different about the silver version?
Only the colour of the decorative panel that frames the station. Box, fixings and fit are the same (AK-R20INWALLK).
Can I add a rain hood?
Yes. The black R20A / R25A in-wall rain hood fits onto the decorative panel before the station goes into the box; it is sold separately.
What is in the box?
The flush-mounting box, the decorative panel, four M3×6 screws for the station, two M4×15 Torx locking screws, four ST4×20 screws with wall anchors, and a Torx wrench.
Match the frame to the door phone.
Choose black to suit the black R20A or R25A; the silver kit (AK-R20INWALLK) has the same box and fixings with a silver frame.
Installation & safety notice
For the strongest result Akuvox recommends screwing the box to the wall and filling the gap with cement or non-corrosive adhesive; setting the box in cement alone is quicker but less vandal-resistant.
