When you are retrofitting a 90-degree corner workstation, the Corner Diagonal Plate is required to allow proper installation of a corner keyboard tray and adjustable arm mechanism. Once you have a corner diagonal unit installed, you’ll be able to mount a 22″ or 28″ arm mechanism along with a corner keyboard platform. The diagonal plate creates a flat 45-degree mounting surface across the inside corner of your desk, giving you the clearance needed for the mechanism and tray to swing freely.

When You Need This

• Corner workstations where the inside corner is less than 12″ deep
• L-shaped desks being retrofitted with under-desk keyboard trays
• Any 90-degree corner where a standard mechanism mount won’t clear
