CTA Digital's VESA-Compatible Keyboard Tray add-on makes it simple to use an external keyboard to a tablet. This L-shaped bracket lets users easily mount a tablet enclosure (like CTA's popular Paragon line of enclosures) to walls, mobile floor stands, or anyplace a digital workstation is required. The back plate comes with pre-drilled mounting holes in a standard VESA 75 x 75 or 100 x 100-milimeter pattern. Cables can be easily routed through the circular opening. The bottom bracket safely holds external keyboards in place with slip-resistant foam padding. This useful bracket and tray holds monitors or screens up to 13 inches.
