These post caps make a very good impression! I had already looked around in local hardware stores and all I had seen there was a maximum of simple, galvanized steel and in addition also still poorly gefertig and expensive. These post caps are surprisingly well made. In conjunction with the low price I'm thrilled! The caps could be easily mounted (Edelstahlschrauebn have to arrangements). How well the "stainless steel" actually is, I can not say in momnet: I had acquired in the past from another dealer conveniently a Mailbox Stainless Steel, who had unfortunately recognized at the time a certain amount of rust ... looks now simply no longer chic from. To prevent such a thing possibly, I have the post caps cleaned after installation (free of fingerprints and other fat) and sprayed with PTFE spray. I have therefore done in the past with other metal parts good experience. The coating is not really seen, repels water and seals the surface. Maybe I can say after the winter more.
