Our bedroom furniture is 40 years old. The threads on one of the knobs wore out so i had to replace all the knobs for a matched set. I ordered just one pair of these to try. They have a longer shank. They are easier to pull than the old knobs, and they are a nice update for the old furniture. The finish is just right. They come with one short screw option and one long screw option that can be shortened. I ordered more knobs to finish replacing the old knobs.
