Reply to comment by adventure_in_gnarnia in How to mount something safely on a wall of unknown material? by zeurydice

Its not what the anchor can hold, it’s about all the assumptions everyone is making about the construction of the wall itself. OP says it’s 3” thick and has potentially 2 layers of drywall on one side. OP also hasn’t been able to definitively identify framing/structure or anything really. It will probably be fine but no one here has enough info to say for sure. There is lots of janky shit out there in the world of older construction and DIY.

Toggle bolts rely on the strength of the parent material, not the anchor itself. Doubled drywall should be even stronger. The wall basically has to buckle around the anchor to fail. I’ve hung a large TV on articulated arms (think lever arm on bolts), in a 100 year old lathe-and-plaster construction house with four toggle bolts, and no stud mounts. A pot holder should be fine.

What’s the worst that can happen, OP has to patch a wall? … it’s not like a potholder is gonna bring down the ceiling

I understand how toggle bolts work, lathe and plaster is also generally significantly stronger than drywall. All I’m saying is this wall is suspiciously thin and op can’t even find framing in it. I’ve seen “walls” where the top and bottom plates were fit with friction. Like I said, it’s probably fine but I certainly have questions.
