Offering a superior writing surface and unsurpassed durability, M1 Dry Erase Board with a 28-gauge porcelain-on-steel surface is mounted to a 3/8" thick backing for added strength. Durable, porcelain-enameled surface keeps the dry-erase board from scratching or denting, even when installed in high-traffic schools and offices. Wear-resistant surface does not absorb ink, eliminating staining and ghosting that would otherwise result from repeated use. Easy-to-wipe board requires less cleaning, achieving a long-lasting, bright-white surface without the hassle. Board comes in sleek, satin aluminum frame with an accessory tray and protective endcaps. SmartPak tray minimizes clutter and keeps items within reach.
