In architecture, a "pecklesteiner" is a set of doors that overlap each other when closed, and can be locked through a single keyhole.

The story behind the answer

False. “Pecklesteiner” isn’t a recognized architectural term in dictionaries, building codes, or standard design references. The described setup—door leaves that overlap and can be secured via one lock—would typically be called rebated double doors (with a meeting stile) using a single mortise lock, or French doors with a multipoint or espagnolette-style mechanism, not a “pecklesteiner.”

Helpful context: Door jargon covers real features like leaves, stiles, rebates/rabbets, and astragals, and types such as bifold, accordion, pocket, and French doors. A good memory tip: if a term sounds exotic but doesn’t appear in reputable sources, it’s likely a red herring. Think “peckle-what?” to remember it’s not a thing.
