I wanted to use this on a dresser front. I found that they don't even work with back adapters in this app due to the size of my handmade dresser. Too wide, a little too deep. I need to add some 1.25" washers to use them as intended. But whatever, good price. To edit. Made spacers and they worked. ensure that the drawers fit snugly against the paneling. They can be tricky to install, but they worked well. My advice is to line up the guides BOTH VERTICALLY and HORIZONTALLY on the front of the dresser. Use only 2 screws in the slotted holes and add one in the middle once you have it where it needs to be.
