Akuvox R27 / R28 in-wall kit flush-mounts an R28A or R27 door phone. It contains the flush-mounting box that goes into the wall, the flush-mounting bracket the station hangs on, and the screws and anchors to fix them. The door phones ship without mounting hardware, so a flush install needs this kit.

Box, bracket and fixings.
The AK-R27R28INWALLK is the Akuvox in-wall installation kit for the R27 and R28 series. Akuvox ships the door phone without mounting hardware and packs the flush-mounting parts in this kit.
Mounting hardware only.
Everything to flush-mount one R27 or R28. The door phone and the in-wall rain cover are sold separately.
- Flush-mounting box

- Akuvox R28A or R27 door phone

A cleaner front entrance.
A recessed R28 sits close to the wall with its cabling hidden — the usual choice for apartment lobbies and new builds where the recess can be planned in.

What you get
Box plus bracket.
The flush-mounting box lines the wall recess; the flush-mounting bracket screws into it with M4×10 screws and carries the door phone.
The station hooks over the top of the bracket and is locked from underneath with its two M3×6 hex socket screws.
How it works
Fitting the kit.
01
Cut the recess
Cut a 262.5 × 121 × 60 mm (H × W × D) hole, slightly oversize so the cables fit.

03
Fit the bracket
Screw the flush-mounting bracket to the box with the M4×10 screws.
04
Hang the station
Hook the door phone onto the bracket, press down and lock it with its two M3×6 hex socket screws.

Answers
Common questions
Does the R28A come with mounting hardware?
No. Akuvox packs the wall-mounting and flush-mounting parts in separate on-wall and in-wall kits.
What size recess do I need?
Akuvox specifies 262.5 × 121 × 60 mm (H × W × D) and advises cutting it a little larger so the box and all cables fit.
Does it fit the R27?
Yes. Akuvox’s R27 and R28 quick guides list the same in-wall kit contents and recess.
How is the door phone secured?
It hooks over the top of the flush bracket and is locked from underneath with its two M3×6 hex socket screws, using the Allen key supplied with the door phone.
What mounting height does Akuvox show?
The Akuvox R27 / R28 drawings place the camera centre at 1,500 mm and the bottom of the panel at 1,259 mm above ground.
Which rain cover suits a flush install?
The silver R27 / R28 in-wall rain cover, fixed together with the bracket.
Is the door phone included?
No. The kit contains the box, bracket and fixings only.
Surface or flush — pick the kit.
For surface mounting use the R27 / R28 on-wall kit (AK-R27R28ONWALLK) instead.
Installation & safety notice
Akuvox also describes a simple install with the box set in cement or adhesive (lower vandal resistance); fill gaps with waterproof material to keep water out of the back of the door phone.
