Place your mouse at a more comfortable, ergonomic height while adding a convenient place to stash pencils, paper clips, and other small items. The Clamp-On 360 Degrees Swivel Out Mouse Tray with Storage suspends your mouse approximately 2.25” beneath the surface of your Stand Up Desk Store standing desk, reducing desktop clutter while positioning your hand in a manner that minimizes fatigue and potential for pain. Thoughtful features of this ergonomic mouse platform include a swivel design that perfectly situates your mouse when you need it, and swings it out of the way and out of site when you don’t. The generously sized mouse pad area is flanked by two recessed bins for storage of commonly needed items like pens. Lifting the pad gives you easy access to a third compartment, ideal for items needed less frequently, such as rubber bands and extra sticky notes. Installation is effortless and tool-free, thanks to a robust, integrated mouse pad clamp and thumb screw which securely attach the mouse tray to the desktop surface. Works with all Stand Up Desk Store standing desk models, plus many similar products from competing brands. Offers an ideal complement to the Clamp On Pull Out Keyboard Tray.
