Box Man, Inc’s white tri-fold display board with header panels are unlike your standard science fair or exhibit boards from an office supply store. We created ours to have proportional panels that are taller than a typical white science fair display board, and we created a header panel to add on top. This way you can proudly display whatever your project is without cutting into precious space on your display. What sets apart our white science fair display board with header from typical ones you find at an office supply store are the dimensions. 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. Whatever project you have coming up, be it National History Day or a science fair, Box Man, Inc has the white tri-fold display board with header panels you need in stock.
