StarTech.com ARMUNONB1 Height-Adjustable Laptop & Monitor Arm

Brand:

StarTech.com ARMUNONB1 is a full-motion, height-adjustable desk mount designed for enterprise workstations, IT desks, control rooms and space-constrained professional environments. It supports a laptop on its 12.6 x 9.5-inch tray or one VESA-compatible display up to 34 inches and 8kg, with spring-assisted height adjustment, 360° rotation, cable management and a hand-tightened C-clamp.
