Transom Frames Product Guide

The framed section above a door is called a transom. It may contain glazing or a panel and can provide a visual connection, borrowed light or a coordinated opening design. Custom Metal Products offers transom frames within engineered opening assemblies, including glazed or paneled options and profiles suited to commercial construction and fire-rated entrance applications.

A transom is the horizontal framed element above a door or window opening. A mullion is a vertical member that separates or supports adjacent openings, such as a door and sidelite. In commercial hollow metal assemblies, both can be coordinated within sidelite, transom and window frame configurations, depending on the opening layout and project specifications.

A transom door closer is hardware used with a transom-style door assembly to control the door’s closing movement. The closer selection and installation depend on the door, frame and hardware specifications. Transom frames themselves are the surrounding hollow metal components above or around the opening, and they should be coordinated with the complete door and hardware schedule.

Available assemblies include sidelite, transom and window frame configurations, with glazed or paneled options. Products can be supplied as welded or cut-and-notch assemblies where applicable, and standard or custom profiles are available. Project configurations may also include arched, radius or segmented frame options, subject to the selected product and specifications.

Yes. The product range includes UL fire-rated hollow metal construction for transom, sidelite and window frame assemblies. Fire-rated openings must be specified and coordinated as complete assemblies, including the door, frame, glazing or panel components and related hardware. Product selection should follow the applicable project requirements and listed configuration.

Provide the opening layout, required frame type, dimensions, glazing or panel preference, assembly method and any fire-rating or healthcare requirements. It is also useful to identify whether the project needs a standard or custom profile, sidelite coordination or a specialised configuration.
