Why are there two different sizes of Versa-Stops?

Versa-Stops are intended to act as stops for materials while cutting. To do that, the stops are placed as far apart as the workpiece will allow, and the workpiece is butted against them. Whenever possible, one of the Versa-Stops should be positioned under the Guide Track. The shorter stops are designed to fit under the track easily. The tall stops are positioned in other holes in the table, and offer extra height for maximum workpiece support.
