The roll of paper towels that this rack was made to hold is about 18″ round. The axle shaft of this paper towel holder is 7.5″ off of the wall after it is hung up. So it is so tight to the wall you can’t pull towels off the roll. So what every you are paying your engineers, is too much and you need to fire them and hire me.
