These slides look good, unfortunately they suck. I've spent at least 20 hours working on these things. The working mechanism is plastic and breaks. I broke 3 out of 6. You keep tripping over the soft closing of the slide where it no longer pulls the box into the closet. You must then remove the drawer to reset the slide. A bright light - I called the company after the first one broke and they sent me a replacement. I have built many cabinets and installed many drawer slides over the years and have NEVER faced a more frustrating task than this. Right now I'm only working with 6 drawers and I'm going to take the back and kick that shit out. I will always associate Liberty gear with junk from now on.
