Ubiquiti Unifi U6+ Mount To Octagonal Box

This is a mounting bracket to mount a Ubiquiti U6+ Access Point to a 4 inch octagonal box.

Nov 2025: I added a version 2 that I'm hoping will work with either an octagonal junction box or the normal rectangular work boxes. I'd appreciate some feedback as to whether or not it works as I no longer have access to an AP like this to test with.

I made this for a customer of mine who had an octagonal steel junction box in his ceiling that his ethernet cable came out of. There was no way to install the access point with the Ubiquiti supplied mounting solution in a way that the entire box would be covered and look nice, so I made this 3d printed solution.

The outer holes should screw to the threaded holes on the junction box. You should only need one pair of holes, but I put in three pairs so there are three angles to choose from in case one angle works better than another. They are inset compared to the other screw holes because otherwise the screw heads would interfere with how the access point clips in.

The mount supplied by Ubiquiti should screw to the inner ring. Make sure it is positioned correctly so that when the access point is clipped in the ethernet port lines up with the cut off side of this circular bracket, as this is where the ethernet cable will pass through and plug in.

Unfortunately I did not do the install myself, but I was told this bracket “worked liked a charm”. Please let me know if you have any trouble using it. I created it by referencing the cardboard template that came with the access point and by googling the standard dimensions and screw locations of an octagonal steel junction box.
