The Martin® Onyx Utility Side Tray is a great addition to any drawing table as it keeps tools easily accessible without forfeiting workspace. It affixes aside any 23.5” deep table edge with wood screws and measures just 23.5” x 6”. Three (3) recessed pans hold smaller items while six (6) wells keep drawing instruments upright. This tray also features a swinging cup holder for additional tools or water bottle and has a locking mechanism to keep stationary when needed. Supplies pictured are not included.
