Glides are good, but  the screw heads are larger than the opening where the screws go! They need to add instructions on how to install the screws!

After removing drawers several times during installation one slide jammed and I noted 2 bent tabs that hold the bearings. I managed to put the bearings back and bend the tabs so it would operate but also noticed 2 other bearings missing in the back. They were probably never there. Also the grease coating the slides was pervasive and got on the drawers. The slides are strong and I hope they will give no other problems but I would choose another brand since I think the design is not that great.

I make furniture, so I ordered this item to make a file cabinet. After installing the drawer slides, I opened and closed the drawer, and the bearings started to fall out of the slides. I contacted Rockler, and they immediately shipped me out different drawer slides. They did not charge me anything extra. I can't say enough about Rockler's customer service.

I like the new design of the self-closing mechanism. But then I installed them on the three drawers I was using them on. I thought they were great until I tried to open and close the drawer. The self-closing pin in the mech is longer than the slide its self. So when closing the drawer it won't go by the pin that is out farther then the slide its self. I had to chisel around the back part of the drawer to let the pin hook into the slide to close it. I would of sent them back, but had to get this job done so I just dealt with. Won't order next time.
