No gaps when connecting 2020 profiles. Highly recommend for anyone building a workbench.
Description
This 90-degree triangle fastener serves as a corner fitting accessory for joining aluminum profiles at right angles in frame construction projects. Crafted from durable aluminum, this angle bracket connector features a triangular design to ensure stable and rigid joints. It is specifically engineered to be compatible with 2020, 3030, or 4040 series profile slots, though the exact size variant should be verified against your specific order.
