These ergonomic keyboard trays include an articulating arm, keyboard clamp, and a palm rest. The clamp will secure most keyboards and is easy to operate. After loosening the single knob located on the underside of the clamp, place your keyboard snug between the rubber grips and tighten the knob. To make simultaneous height and tilt adjustments, turn the adjustment knob counter-clockwise to unlock, find a comfortable position, then tighten the knob to hold the desired position.
A 360-degree rear swivel and track mount allow the mechanism to slide out-of-view, below the work surface. More importantly, Econo adjustable keyboard trays can accommodate the position that is most comfortable to you!
