Oberrahmen

Oberrahmen is a term used in German carpentry and joinery to describe the upper horizontal member of a frame. The concept appears across various applications, including window frames, door frames, furniture construction, and picture frames. In a window, the Oberrahmen forms the top boundary of the frame opening and provides support for the glazing, glazing beads, and the upper sash, and it may incorporate weather sealing or drip features. In doors, it constitutes the top rail of the door frame and helps bear loads and align the door leaf.

Materials and construction: Oberrahmen can be made from timber, metal, or plastic, depending on the application. It is typically joined to the side jambs by mortise and tenon joints, dowels, screws, or metal brackets. In modern frames, the Oberrahmen may also include integrated weatherstripping or mounting channels for hardware, and may be part of a larger frame system rather than a single piece.

In cabinetry and furniture, the Oberrahmen refers to the upper frame member of a panel frame or door, providing structural support and a mounting surface for hinges or decorative elements. In picture framing, the top member completes the rectangular surround and carries decorative molding.

Etymology and usage: The term combines Ober (upper) with Rahmen (frame). It is most common in German-language technical literature and in the construction sector; in English texts the equivalent term is top rail or upper frame member.
