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. Stocked in Australia by Infront Technologies.

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.
02
Fix the box
Mark six holes through the box, drill 6 mm, fit the anchors and fix the box with six ST4×20 screws.
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), cut slightly larger so the cables fit.
Does it fit the R27?
Yes. Akuvox’s R27 and R28 quick guides list the same in-wall kit contents and recess.
Surface or flush — pick the kit.
For surface mounting use the R27 / R28 on-wall kit (AK-R27R28ONWALLK) instead. Order through Infront Technologies for Australian stock.
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.
