Review on FRMSAET Furniture Accessories Office Product Suits Hardware 20/24/30 Inches Keyboard Drawer Tray Wood Holder Under Desk Adjustable Height Platform. (20 Inches, White) by Julie Geier

This will fit the glass top Costco standing desk if you flip the attach bracket to face inward, not outward like instructions say. There are two different height brackets supplied. The taller bracket will allow you to fit a raised ergonomic keyboard and vertical Evoluent mouse with room to spare.My only issue is the roller groove of the slide with the ball bearing grease is exposed when the desk is pulled out. If you put your fingers over the edge, you can get grease on them. The attachments points on the sliding tail are permanently attached and cannot be moved to fix the problem.
