After seeing Tim McKnight’s design for a PVC whiteboard rack, Modeler Art Zadrozny came up with the following version:
Cost: $15 for materials, 1/2 inch PVC, including 2 clamps to secure rack to wall.
PVC cement recommended to handle student use.
Time to construct: 10 – 15 minutes, if you have a table saw.
Overall size: 24″ high x 18″ wide x 4 – 5″ deep rest for whiteboards
2 – 3 ” high vertical supports to hold whiteboards in place
