ᐅ Unifi NanoHD on a Concrete Ceiling – What Type of Junction Box Should Be Used?

Hello everyone,

I’m wondering what type of mounting box would be best to install in a precast concrete ceiling to easily mount a Wi-Fi access point (the plan is to use a Unifi NanoHD, or possibly the already available Access Point AC Pro for now) without a suspended ceiling.

The architect suggests a HaloX 180, but that seems a bit excessive to me. Especially if, at least in the longer term, the NanoHD is going to be mounted on the ceiling. It only has a diameter of 16cm (6.3 inches) and therefore might not fully cover the HaloX or its mineral fiber panel.

Is it possible to install a standard flush-mounted box in such a precast concrete ceiling (apparently from Dennert, if that’s relevant)? I imagine it could be used to house the CAT cable, keystone jack, and a short patch cable, with the access point then installed on top. Would there be enough space for that?

Are there any better solutions?

Thanks in advance!

Yes.
1.) The access point is on the ground floor.
2.) The access point is on the upper floor. The cover grill will be screwed in tomorrow.
I have also prepared additional network cables for more access points.
However, it seems that these two, together with the FritzBox in the utility room, are sufficient.

There is so much available, really interesting.

If you like the design and the performance is sufficient, then everything is fine.

For me, with technical devices like these, performance is more important than appearance. The 2.4GHz network will have a long range, but your installation won’t be beneficial for the 5GHz band.

Hello everyone,

I’m joining the discussion here as well. Here’s my situation: I bought two AC Pros at the end of last year. Since the temporary setup (Fritzbox in the living room and a repeater) worked reasonably well, I left it as is for the time being. However, I now want to move the Fritzbox to the basement soon and put the access points into operation. For the ceiling of the upper floor (drywall), I don’t see a problem. I can just hide the installation cable with a keystone jack and a short patch cable inside the ceiling.

In the lower floor ceiling, out of ignorance, I left the installation cable hanging directly from the ceiling. No outlet, no conduit, nothing. Since the access points have little space for cables, I wanted to screw some kind of adapter plate (2–3cm (1–1¼ inches) thick) to the ceiling in between. I remember someone here did something like this before. Unfortunately, I can’t find any ideas on how to build or implement this easily and without much effort. Does anyone have an idea or, even better, a ready-made solution I can replicate exactly?

Thanks and best regards,

Stefan

If I remember correctly, he had a ring 3D printed back then. Alternatively, I could also imagine milling something like that out of wood and painting it, or cutting a piece of plastic pipe depending on the diameter.

I have also considered printing it. However, I wonder if the print might break when screwing it in?!

Using wood would be the easiest to fasten, but it’s difficult to work with without the proper tools. I also have concerns about securing it if I use a pipe...
