I've got this small thing (see attached pictures) in my wall that previous tenants have simply painted over. It's about 1 inch in diameter and has two smaller bumps on it. It also has two protruding notches on either side, one of which is visible in the upper right in the image. It feels rather hard and solid. Magnets do stick to it.



I'd like to pull it off/out of the wall, but my concern is that it might be something where it would be unsafe for me to do that or would be better left to a professional. In particular, I'm concerned it may be some old relic of the knob and tube which I know exists in my building. It could be a completely random/innocuous object, but I want to play it safe.



I've got two related questions.



  1. Can anyone give a guess as to what this is?

  2. If no one can determine what this is from the pictures, is there a way I can try to investigate this to determine if it's safe for me to pull off/out of the wall?

If it matters, the building is from the 1890's.

    @MikeWaters This is on one of the walls in a bedroom. About 5 feet off the floor. This room is a third floor room. I don't know enough about the history of the house to know if they had gas lighting fixtures, but it's not impossible I think.

Given age of building, shape and "magnets stick to it" I'm going with old gas pipe.



Old gas pipe is not generally something you want to mess with, especially if your use of "tenants" implies rental rather than ownership. Hang a picture so it's covered, or something like that, and forget about it.



If you own rather than rent, and can trace and verify that the gas pipe in question is ACTUALLY, for sure, disconnected, you can remove it, but it's a fair amount of work.
