It is a riser, which prevents the bow from bending in the handle area. It also makes the handle more comfortable. I like bend in the handle, but on some bows I think it is safer to use a riser because you have to cut in maybe too much to get the handle narrow enough so the arrow can do its archers paradox thing.
I do not like high risers. This is just a half inch thick and yes it is glued on. The glue is tite bond 3. I would not use a riser on a D bow under 45lbs and/or less than 1 3/4 " wide. Untill one breaks in the handle that is
