The Quad "2 Over 2" 100 Series Desk Stand is an expandable, modular, tool-less Freestanding monitor mounting solution which allows four monitors to be positioned in a seamless 'grid' or 'square' orientation. Each row has a 25" wide crossbar accommodating up to two 24" monitors (measured diagonally bezel to bezel). This unit has 4 Sstandard Quick Release Pivots which are capable of tilting 20º up, 10º down and 25º left and right. This allows the user sufficient range of movement to ensure monitors are in almost any desired position relative to each other in addition to the capability of rotating from portrait to landscape orientation. The pivots are VESA 75 and 100 compatible and can be moved along the crossbar, or removed from the stand in seconds. The heavy weighted 18" wide x 16" deep Heavy Duty base is 29 lbs and the vertical pole is 28".
