In section. Slots cut through the wall.

Longitudinal slots, cut through the full wall of the liner.

A straight slot is the same width all the way through. A keystone slot is narrowest at the outside and opens inward, so a grain that enters it does not lodge.

Drawing. The slot is drawn far wider than true.
