LONGER LENGTH POLE: The DM45/55 80cm extra-long pole gives additional height to your screen/s. It is double the size of our standard-sized poles and can accommodate multiple screens. Depending on the screen size of your monitor, if you use articulating arms you will be able to position them closer to you, move them together or away from each other and adjust the height of them on the pole. STRONG V-SHAPED CLAMP: Included with this longer pole is a strong V-shaped clamp which provides extra stability for a heavier load. This wider clamp can fit tables with a depth of between 5mm and 68mm. If there is no space at the back of the desk for the clamp to fit, you can purchase a Duronic grommet to enable you to mount it on the top of the desk via a hole, or use the cable management hole that is available on most office desks. PART OF OUR ERGONOMIC RANGE: This pole is part of our office equipment range which offers workstation solutions for everyday life at the office or at home. Our popular desk mount range allows the user to achieve optimal viewing angles of their screen, as well as allowing the adjustability to fully customise their desk set up.
