Panel, slab, and ledge are all types of:

• A. Wood swinging doors.
• B. Metal swinging doors.
• C. Overhead rolling doors.
• D. Revolving

Answer: (A)

Panel, slab, and ledge describe wood door constructions that are designed to swing on hinges. A panel door is built with a frame and inserted panels, giving it a classic, sturdy look; a slab door is a flat door without a pre-attached frame, meant to be hung in an existing doorway; a ledge (ledged) door is made from vertical boards held together by horizontal ledges or braces. Because these terms refer to wooden doors built to swing open, they best fit the category of wood swinging doors. They’re not about metal swinging doors, overhead rolling doors, or revolving doors, which are different types of door systems.
