I'd hate to hold a cover plate while removing 1/4" of material with a belt sander. The chop saw is a better solution.
The main difference is that the chop saw will instantly remove all the finger that it's going to remove, while the belt sander would remove about a millimeter at a time.
The "frame" kind of thing is pieces of molding, about 2" across, making a rectangular pattern on the order of 18" high by 2 to 5 feet wide. It's nailed and glued to the wall.
The pity is that the electrical stuff was already on the wall when they mounted the frame pieces and they didn't even try to center the fram between the electricals.
