This set features robust "L-shaped" plates (corner braces) designed for reinforcing 90-degree angles. They are the essential final piece of my heavy-duty structural connector series.

Like the T and Cross versions, these are built to be structural. With a 4mm thickness and 20mm width, they offer excellent rigidity for squaring up frames, repairing furniture corners, or building custom enclosures.
