Our corner application keyboard trays are designed to fit 90 degree, diagonal, and radius corner workstations. They are constructed using a dense, laminated wood composite material (MDF) and feature smooth radius edges and a covering that has excellent feel and traction for mouse operation. Slimline trays are 3/8" thick and have pre-drilled through-holes for mounting. All other keyboard trays are 5/8" thick and are fitted with threaded inserts for mounting to articulating arms (sold separately in the ARTICULATING ARMS ONLY section). Corner trays include a Sunway Premier wrist support for optimum comfort. Remember when choosing a KEYBOARD TRAY from this section, to choose from our selection of keyboard arms (ARTICULATING ARMS ONLY at left) to complete your system.
