Ageless Iron Keep Plate Passage with Tine Lever - Black Iron Right-Handed Door Hardware for Home Security & Vintage Style" （注：原中文标题已翻译为英文，并增加了使用场景描述）

Ageless iron door handles have options for 2 different tongue offsets (2 3/8 & 2 3/4) as well as advertising they fit up to a 2” thick door. THIS product is ONLY for a 2 3/8 offset that is on a 1 1/2 thick door, and my door was 2 3/4 and 2” thick. I had to order another tongue as well as purchase longer screws as well as a longer privacy latch pin to get it to work. Overall, it was just NOT worth the effort. If you want an ageless iron handle, go to the vendors website to order.
