80/20 aluminum extrusion builders, this 40 Series 2-hole inside corner bracket is exactly what you need for creating strong, precise 90-degree joints in your projects! Measuring 40mm x 40mm with a 6mm thickness and 36mm length, this clear anodized bracket is made from 6063-T6 aluminum that's both strong and lightweight. The two 8.3mm diameter thru holes work perfectly with recommended #13-8316 and #3838 assembly hardware (sold separately) to create vibration-resistant connections that activate the 2-degree locking feature on most 80/20 profiles.

The quality is top-notch with smooth deburred edges, tight tolerances, and that durable anodized finish that resists corrosion and looks professional. These brackets are compatible with 40 Series aluminum extrusions and many competitor's 40mm-based profiles, making them incredibly versatile for various projects. Whether you're building shelving units, workbenches, machine guards, 3D printer frames, or any structure using t-slot aluminum, these corner brackets provide the rigid, reliable connections you need. They're easily removable and reusable too, so you can reconfigure your projects as needed. The 90-degree angle is perfect for frames and structures, and the inside corner design keeps your joints clean and professional-looking. If you work with 80/20 or similar aluminum extrusion systems, having a supply of these quality corner brackets is absolutely essential for building strong, square structures that stand up to use.
