Expanded flange inside corner control joint

#30 Corner Master™ Expansion/Contraction Control Joint (Double-V) is designed to provide stress relief at inside corner intersections on plaster walls. The Double-V expansion joint absorbs movement resulting from expansion and contraction of plaster walls and controls cracking.
