Help identifying unknown outlet


While doing renovation at my 30 year house I opened blank plate on the wall and discovered this strange outlet inside. It is not wired and there is no wires inside. Shape is very strange so I have no idea what is the purpose of this outlet. I did not find anything similar in internet.
You may notice it is located very low comparing to normal electrical outlets.
Any idea what is it and what it serves?

Well that certainly is an interesting looking whatever-it-is. Can't say I've ever seen one before. I suspect it might be a cable pass-through, meant to allow some kind of low-voltage cable (cable TV, speaker wire, intercom?) to come out of the wall. Can you remove it and take a few more pictures of it from the other sides?

I'm with mcsteve on this. I'm pretty sure in older times they they didn't have wall connections for TV cable. I believe it was just ran into the room. With that outlet you have, it allows the cable to pass through without chaffing it. But this is just a wild guess lol

My dad and grandpa however just ran theirs directly to the TV in the room. If you wanted the cable out of the way you feed it back into the basement lol.

If there are no places to 'wire' anything to it on the inside, I'd guess it's for the old analog TV antenna wire. The 2 wire, flat plastic TV antenna wire with the spade connections would slip in and out of that easily enough, hence the 'oval' shape?

Old telephone jack. The wire from the telephone went thru the plastic hole and had a metal prong that would keep it from being pulled back out. About 1950 to early 1960 vintage.

I am with the folks that say this is an old telephone jack. Years ago, what we now call a headphone jack, IE a 1/4 inch PHONE plug:

Was commonly used on telephone switchboards. These were also used occasionally in home telephone sets, along with the 4-prong terminals that came out in the 40's:

I'm not quite so sure it is for phone....

Can you take pics of the back of it? If it has light gauge wire to it..then it is phone..but it does not look deep enough for a TRS (Tip Ring Sleeve) plug to go into it...additionaly, the TRS female socket will have a ground right at the neck surface....if that was a phone plug, I would expect to see wear marks in the hole.

Look at the odd shape of the hole....not a true circle.

Look at the screws holding the box....square head....not exactly 1950's construction....that looks to be pretty recent.

I took it out.
Made pictures by phone so sorry for poor quality.
It has 6 contacts on the back which are not through to the hole. The hole inside is only plastic without any contacts. It seems like a pass for wires into the wall were they are connected with other wires probably.
There is also central contact. This contact can be accessed by some long metal connector.

That is a low voltage device. Could have been used for a phone....but I'm more inclined to think it was for a device that was intended to stay plugged in all the time. Unusual to do that with phones...might have been for a fax machine....

Was the house owned by an old person before? It might have been one of those life monitors.

Is the back screw and "C" clip on any type of spring?

I see #s and letters too, have you searched those yet?

Telephone hard wired outlet. I worked as a telephone installer 1965 to 1968-installed many of them. This was the era before plug in telephones.

That device is not from the 60's, at least not in that nice looking condition. And no way would any one renovate and reinstall a device from the 60's... Lol..
