A non-fenestrated drape is one that does not have an opening or window to expose a specific area for surgical access. The U-drape is classified as non-fenestrated because it is designed to cover areas around the surgical site while leaving the center undraped, allowing the surgeon to access the area without any specific openings or fenestrations.

Other types of drapes, such as the fenestrated drape, include cut-outs that provide openings for surgical procedures. The Chalazion drape is specifically designed for ocular procedures and may also have a central opening, categorizing it as fenestrated. A split drape is specifically designed to cover the body while allowing access to the extremities or certain areas through narrower openings but is still not categorized as non-fenestrated. In contrast, the U-drape's design is purely for encompassing areas without specific perforations, aligning with the definition of non-fenestrated drapes.
