I bought these slides to replace the ones on my dresser. Somehow during the move the drawers slipped out of the dresser and the sliders were damaged or lost. They weren't the size that came with the dresser but they fit perfectly as a replacement. When I started the installation I had a hard time getting the screws in. I had to π€ what I could do without calling anyone for help. Which would take weeks. So I looked in my tool bag and found a mini screwdriver πͺ and a hammer π¨. I used them to start the screw hole. Once I did it was easy. The rest of the installation didn't take long. Less than an hour. Attached the boxes and they are perfect. In fact, they open and close better than the originals. I gave 4 stars because I had trouble getting the screws in. Next to. no problem
