Unlike your traditional science fair or exhibit boards from an office supply or craft store, black tri-fold boards with header panel from Box Man, Inc have proportional panels that are taller than a typical board and include an additional panel for the title. This additional header panel gives you the ability to proudly display a name for your project without cutting into the valuable space on the rest of the board. Our double-wall corrugated boards are 72 inches wide and 48 inches tall, and when opened and on display, there are 23.5-inch-wide side panels and a 25-inch-wide center panel. The title panel extends across the exhibit board to a 40-inch width and is 10 inches tall. Make your National History Day or a science fair project stand out with Box Man, Inc’s black tri-fold boards with header panel.
