Your staff keeps reaching around paperwork and monitors to switch between keyboard and mouse work; a desk keyboard tray belongs in that workstation review. If every desk is arranged differently, your team spends working time adapting to furniture instead of moving through the task in front of them. Shared offices make that problem more visible: one person may need room for active documents, while another needs the keyboard and mouse positioned for a different routine. You are also buying for a measured footprint, not an abstract category, so width and depth matter before you approve a quantity. This tray's separate keyboard and mouse measurements give you concrete dimensions to compare with each desk, monitor, and paper workflow.
The unit includes an MDF keyboard and mouse tray, along with a molded PU palm rest for keyboard systems. The keyboard tray measures 20-1/2-inch wide by 11-inch deep. The mouse tray measures 7-1/2-inch wide by 8-inch deep, giving you a second set of measurements to review when planning placement at each workstation. The slides lock into the fully extended position, preventing the keyboard tray from moving during use. That specification matters when your staff is typing, reaching for the mouse, or returning to the keyboard repeatedly throughout a workday. You can review the keyboard tray and mouse tray dimensions separately rather than treating the entire arrangement as one unmeasured accessory.
For your purchasing process, start by comparing the 20-1/2-inch keyboard tray width and 11-inch depth with the space available at each desk. Then review the 7-1/2-inch mouse tray width and 8-inch depth against the area your team uses for mouse work and active paperwork. The molded PU palm rest is included with the keyboard tray, while the slides lock when fully extended to keep the keyboard tray from moving during use. That gives you a clear configuration to specify: an MDF keyboard and mouse tray, a molded PU palm rest, separate keyboard and mouse measurements, and a locking fully extended position. You can order against those facts and set a consistent workstation standard based on the dimensions your office can accommodate.
