The corner keyboard tray by ESI has an 18.75" wide platform that is designed to be mounted underneath a radius corner worksurface. It has a tilt-and-swivel mouse platform which can be positioned directly in line with the keyboard, closer to the body for extra comfort, or over the keypad to reduce reach. The articulating arm is height adjustable with a +15º tilt adjustment and has 360º glide track rotation. Quality backed by a 15 year warranty on the platform and a 2 year warranty on the palm rests.
