These back panels are 48" x 96" x 3/8". They are primarily to cover the backs of an island or penninsula. The panels can also be used for applications like an angled end an a cabinet run. You can rip them down, to create a finished bottom on some uppers. Box out a hood vent, you could even build a wood hood vent with this material and some fillers. Just about anything that you need matching painted material for, this works great.
