4 x 8 magnetic dry erase boards with grid lines printed onto the writing surface are perfect for schools, sales offices, manufacturing facilities and so many more places.

An extra large dry erase board with a magnetic receptive dry erase writing surface. Each board has 1" wide satin anodized aluminum trim and a full-length marker tray. Each unit also includes installation hardware.

4' x 8' OptiMA grid boards are created with our exclusive OptiPrint™ method which provides for smooth permanent lines. The grids are covered with a special clear material which provides for a great damp or dry erase writing surface that resist ghosting and gives years of trouble free use.

Now available with variegated rows in which every other row is shaded from left to right in light gray or columns where every other column is shaded from top to bottom in light gray for much easier tracking and readability.

We can make any custom grid pattern or add any type of headings to your boards that you need. Contact customer service for assistance.

Tip: It is not recommended to clean these boards with anything containing ammonia which is found in most glass cleaners.
