T-Slot Flat Joining Plates

In stock

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.
