They stole that from Hansgrohe, they have used that system for years, as has Dornbracht.I'm more talking about the pull out faucets that take the large mounting nut in the center of the faucet, you run it up close to the top and use the two of three screws to finalize the set.
Dont most pull out faucets mount that way? I cant remember them being any other way.Just yesterday I removed a AM/STD pullout faucet that had this mounting hardware, did not know they use it also.
