16-grit edger discs are the matching pair to the 16-grit drum belts. If you had to sand the middles of your floor with 16-grit on the drum, you will most definitely need 16-grit to sand the edges. This is an extremely coarse mineral; it is designed to hold a large volume of paint, shellac, or lacquer so it can be removed from your floor. It is NOT designed to sand wood to bare. It is a pre-sanding step only. If you use 16-grit until you make bare wood, the next grits in the sequence will struggle to remove the horrific scratch damage that the 16-grit mineral left in your floor. Use 16-grit to remove only about 2/3 of your finish. The 24-grit and 36-grits will do their share of removing the rest, but more gently, without removing any more wood fiber than necessary.
