Junction box fan rated?
Sorry for the crowded and not great photos. House built in 1957 and I cannot tell if this junction box is rated for a ceiling fan. There's no stamps or sticker I can see. But is that a brace (circled in picture)? It's a metal box. Cannot tell if the screws are 10/32. It's in a bedroom that gets very hot and humid in the summer. Thanks for any help!!
