Whiteboard Accessories Marker Tray
Atlas® and Magtray® Dry Erase Marker Trays are engineered for form and function. These trays are a favorite when it comes to outfitting schools, office buildings and doctor’s offices. Their simple, safe and sleek design make them the best option for your next project. 

The Atlas® Tray and the Magtray® are both made in the USA, molded from heavy gauge aluminum and polished to perfection. Using screws and the existing wall studs, Atlas® Trays provide a permanent installation for developing and renovating large office spaces, classrooms and conference rooms. Magtrays® have a highly receptive magnet strip backing that offers a quick and removable application to any magnetic surface, like the fridge or a personal office whiteboard. While both trays are made to last, you can discover the similarities and differences in the table below.

Available in custom cut lengths as small as 18” and as large as 16′, Atlas® Trays are installed into the studs with screws and an electric screwdriver.  These extra long, raw aluminum trays are a favorite among construction companies, developers and other contractors. To maintain fast shipping, our 16’ Atlas® Trays ship in 2 pieces. You can choose from angled or square corners. The smooth angle cut corner removes any sharp corners from the tray for high safety environments. Atlas® aluminum marker trays are made in the USA to order but still typically ship in as little as 2-5 working days.
