Another OptiMA® exclusive! 5' tall x 8' long magnetic dry erase boards with grids. All other magnetic dry erase boards with grids are only 4' tall. A 5' tall board instantly gives you 25% more writing space. Our 5' tall grid boards are part of our series of extra large magnetic whiteboards. The boards are built with a special lighter weight honeycomb core greatly reducing the overall weight of the board making it easier to transport, handle and install. A typical 5' x 8' magnetic whiteboard would weigh up to 140 - 160 lbs. while this unit comes in at 79 lbs. There are four popular grid patterns to choose from including a small 1" x 1", a 1" x 2", 2" x 2" or a larger 2" x 3". That would be height by width on those measurements. Of course you can customize the grid design anyway you wish by simply contacting customer service. Each 5' magnetic dry erase board has a full-length extra deep aluminum marker tray and every unit ships with installation hardware. Normal lead-time is usually 3-5 business days and these units ship by truck.
