Not sure I am in the right place, but I am trying to replace some slide bolts that secure some patio doors. The original ones are inset so that they are flush with the wood. I can find plenty of surface mount slide bolts, and the ones that are installed on the inside of the door, but I can’t anything like the one in the picture. Posting here in case there some one has a name for this style that can help my search, or other websites/businesses that might be a good place to look. Thanks in advance!  Ed
