I bought these adjustable pulls in two sizes - 1 3/8” to 6 5/16” and 1 3/8” to 4”. Our vanity has two drawers 96mm center to center and two drawers along with two doors 152mm center to center. After having trouble finding matching hardware in two different sizes I stumbled across this site and very happy I did. The screws that came with them were too short but I was able to use some of the longer screws that came with the existing hardware. And a quick trip to the hardware store for the remaining screws which for some reason had to be even longer. Not difficult just took a little longer. Would definitely recommend.
