A corner brace is a structural or reinforcing component used to strengthen and stabilize corner joints in construction assemblies.

A corner brace is a reinforcing element installed at the intersection of two structural members to provide added strength, stability, and alignment. It is commonly used to prevent racking, twisting, or separation at corner joints, particularly in framing, cabinetry, furniture, and light structural construction.

In building applications, corner braces are typically made from metal or wood and may be flat, angled, or L-shaped. They are often fastened with screws, bolts, or nails and used in wall framing, roof assemblies, shelving systems, and temporary bracing during construction. In structural framing, corner braces help distribute loads and improve overall rigidity.

From a construction and quality standpoint, proper placement and fastening of corner braces are essential to ensure effective load transfer and long-term durability. While some braces provide permanent reinforcement, others are used temporarily to maintain square alignment until structural sheathing or finishes are installed. When correctly applied, corner braces improve both structural performance and construction accuracy.

Before modern metal hardware became common, timber corner bracing was a key method used to keep early wood-framed buildings square and stable.
