Chalkboards
Only the finest quality porcelain enamel writing surfaces go into our chalkboards. This chalkboard has been time tested for 25 years in schools and universities. We take a sandwich constructed ½" chalk board panel and factory pre-frame it with clear etched and anodized aluminum frames.
Each unit is equipped with a full length chalk tray and full length map rail with 2 map hooks and concealed hanging clips.
