This keyboard tray designed for mounting under a desktop was purchased for $75.60 a few months ago but never used or taken out of its shipping box.  It features:

• 6.3" of height adjustment for a more ergonomic typing position.
• Full motion adjustments allow you to swivel the keyboard 180° left or right, tilt 6° up, and tilt 22° down.
• Gel wrist pad provides support while typing and helps to prevent the keyboard and mouse from falling.
• Large 25" x 9.84" tray provides plenty of space for a full-size keyboard and a mouse side by side.
• Manufacturer's 1-year limited warranty and professional U.S.- based customer support.
