The black LX500 Adjustable Notebook Riser from 3M is designed to raise your notebook computer and hold it at a comfortable height for typing. The height can be adjusted between 4 and 6 inches tall, in increments of 1/2 an inch. This also frees up some desk space, since you can use the space underneath the riser to keep papers or other items. In order to keep your notebook running cool and prevent overheating, the platform has slots that allow air to circulate. The riser features cable management to avoid clutter around your workspace. Side shelves are included for organization. Plus, it comes with an adapter that is compatible with 3M's DH445 document holder in case you choose to purchase this as well. Additionally, the LX500 works with docking stations to help foster productivity.
