3M Knob Adjust Keyboard Tray, Standard Platform with Antimicrobial Gel Wrist Rest and Precise Mouse Pad, 17-inch Track, Black (AKT60LE)

Keyboard tray was relatively easy to install within 15 minutes. Instead of using the the provided template I drilled a pilot hole where the front of the rail system is supposed to be situated and then attached the rail system with a screw. I followed up with the 5 additional pilot holes and secured the rail system using the holes in the rail frame as the template. The rail system does have a little side-to-side play (approximately 5 mm) and the powder coat made the height adjustment difficult which are the reasons I did not give this a full 5 stars. Overall it is a very stable keyboard tray that easily accommodated my oversize macro keyboard (55 mm width) but without the space to use the mouse which is fine since I had not plan on using the mouse on the keyboard tray. I would have preferred a better rail system with ball bearing rollers but this setup is smooth still. Some sort of nylon washers where the pivot points are would have probably eliminated the issue with the powder coating affecting the height adjustment. The keyboard tray in the end served my needs and is very robust so I do not foresee any issues in the future.

I don't see how this thing stows under a desk without smashing the keyboard into the underside of the desk. Stowing is not mentioned in the instructions. I looked for a latch such as is referenced (but not shown) in the ATK50 video but I don't see one. I'll be returning this.
