Reply to comment by BxMxK in Closing off an AC vent by flyingGoatPenis

Agreed. Closing just one duct has tripped my blower fan in the past from the change in air pressure.

Might need a professional for this. But honestly, best thing to do is leave the vent. I don’t see any reason to remove it other than the slight inconvenience of furniture positioning.

I'm assuming you were trying to use something like a tapcon threaded anchor? I personally despise them. Even when I use the factory bits, they tend to jam and break off. I suggest removing the anchors and then drilling the holes out large enough to use glue in anchors. A SDS hammer drill will make quick work of it. Borrow or rent if needed.

What many commercial installers do, and will work for you, is to glue studs into the holes using special epoxy and then mount your post with nuts. If you are in the US, Home Depot sells the Hilti glue (link below) - which I have used and like - you would still need to drill holes and purchase some threaded rod of the correct diameter. Drill the hole a little oversized and then glue the threaded rod into the holes. Let it cure, then attach your posts. The exact length doesn't matter. I would use stainless steel threaded and stainless lockwashers and nuts to avoid corrosion problems.

It can be convenient to make a jig out of plywood and use that to check the spacing and location of the studs are correct before the glue sets.
