Review on Liberty 931605 16 Inch Bearing Extension by Mike Carter

I bought a pair of these rails to replace the keyboard rails on my desk. Those who came to him failed miserably. All the bearings fell out and it started sagging a bit. Not to mention that they really were too small and the tray was never fully extended. Here are the slides. They were about 1/16 inch thicker than the ones I had, so I had to shave off a bit on each side of my tray. However, installation was easy. They slide out completely, giving me full access to my keyboard tray. I can easily place my hands on the tray and don't sag. They roll very gently. When I slide the tray past the "end handle" the rest of the tray slides by itself. All in all I can't say anything bad about them, they do everything I wanted them to do perfectly.
