Slide stop does exactly what its name says; it stop dowels from sliding in and out of holes.
Most TeacherGeek components come with splined holes that dowels press securely into. If you want a dowel to rotate or slide in the hole, you can use a reamer to enlarge it. You will likely then want to use slide stop to keep the dowel from falling out of the reamed hole.
