An A-frame is a basic structure designed to bear a load in a lightweight economical manner. The simplest form of an A-frame is two similarly sized beams, arranged in an angle of 45 degrees or less, attached at the top, like an uppercase letter 'A'. These materials are often wooden or steel beams attached at the top by rope, welding, gluing, or riveting.

A-frames can be used as-is, as part of shears, or set up in a row along a longitudinal beam for added stability, as in a saw horse. More complex structures will often have crossmembers connecting the A-frames at different angles,[1] forming a truss.
A-frame level: An A-frame with a plumb line hung from the vertex, used to establish a horizontal line; known in ancient Egypt, these were used in Europe until the mid–19th century.[2]
At the stern of ships for fishing or research. These may be fixed or luffing. Similar arrangements are used for launch and recovery systems for diving bells, ROUVs and small submersibles from other positions on a support ship.
