The purpose of a concealed Z bar is to connect and stabilize masonry walls, ensuring structural integrity while maintaining an aesthetically clean appearance without visible ties.

Examples of Use

• In brick veneer construction, concealed Z bars secure the veneer to the structural wall, providing stability and preventing separation.
• In cavity wall construction, concealed Z bars tie the outer and inner walls together, ensuring they act as a single structural unit.
• Historical restorations may use concealed Z bars to maintain the original appearance of the masonry while providing modern structural support.
