I had to research as to what this thing is and used for. I found that it is used to anchor pool ladders and such. The metal is cast bronze, not brass. I found the spec sheet for this thingy if that helps anyone
Bronze not Brass. Am I reading the information from the Perma-Cast website wrong?? Info copied from Amazon third party resellers is not always accurate. Yes, this style is available in aluminum. Perma-Cast does not make them in Brass. The metal alloy composition is different between the brass and bronze.
I don’t see a difference between PS-4019-BC and PS-4019-B except one has a limited lifetime warranty.
The catalog then calls these “Brass Pool Products” but offers them in bronze, aluminum, and plastic.
So who knows.
