Figure description:

The image is a cross-sectional technical drawing of a mechanical component. Key information includes:

Reference Point: A horizontal GAUGE PLANE.
Vertical Dimensions:
- H: Height from the top of the component to the Gauge Plane.
- L: Length from the Gauge Plane to the bottom edge.
Horizontal Dimensions:
- S: Width of the top section.
- D: Internal width of the bottom cavity.
Notes: All dimensions are in millimetres. The hatched areas represent solid material in section, and a vertical centerline is indicated.
