Brackets are essential, externally mounted fasteners for T-slot aluminum extrusion structures. They provide strong, highly versatile 90-degree connections, and sometimes even more complex joints. A major benefit of most 80/20 brackets is that they don't require any machining on the profiles, making them exceptionally quick and easy to install, adjust, and reconfigure. You secure them by simply inserting T-nuts into the T-slots and bolting the bracket into place.

Flat joining plates are external fasteners used to connect T-slot aluminum profiles. They are flat metal plates with pre-drilled holes that bolt onto the outside surfaces of profiles using T-nuts. These versatile plates are ideal for creating straight, T-shaped, or corner connections, and a major benefit is they don't require any machining on the profiles, allowing for easy installation, adjustment, and reinforcement of structures.
