Omnimed security Laptop stands are constructed of heavy gauge steel that is powder coated for a durable attractive finish. The Laptop is secured to the work surface with a cover that has two-lock security and an adjustable keyboard tray underneath. The security top is mounted on a heavy gauge plated steel column in a 5 leg base with 3 inch casters. These stands can be used sitting or standing. Vertical movement is controlled by operating the hand levers on both sides of the security top to adjust the height from 35 to 45 inches. A gas spring lift mechanism within the unit provides the smooth vertical lift. Stands measure 35H to 45H x 21 1/2 W x 14 ½D. The base has a diameter of 25 inches.
