#XJ15 Double-J Control Joint

Expanded flange control joint with a taped reveal for a clean finish

#XJ15 Expanded Flange Control Joint (Double-J) is used to relieve stresses in large plastered areas of walls, ceilings, and stucco areas. This expanded wing control joint minimizes cracking and assures proper plaster and stucco thickness. The Double-J has a 5/16” reveal and rolled outer edges to prevent visible separation cracking. The applied plastic tape keeps the reveal clean and is removed easily after the finish application.

Application(s): Stucco

The #XJ15 enables plaster to key into the return lip to eliminate shrinkage separation, a preferred finish feature. The joint is taped, preventing stucco from getting caught inside during installation and providing a neatly finished job upon completion.

The #XJ15 Double-J Control Joint is also available in zinc alloy for increased corrosion resistance.
