Good value, minor finishing issues

Overall very happy with the strength of these brackets. One out of the four had a slight scratch on the surface, but it doesn't affect functionality. Great price for factory direct quality.

Great for European standard profiles

Verified these work flawlessly with my imported European 3030 profiles. The hole alignment is precise. Will definitely order more for my next project.

Essential for CNC frame builds

I've built three CNC machines using these angle brackets. They hold the frame rigid even under vibration. The included hardware is high quality and tightened down nicely.

Solid construction

Very robust brackets. Installation was straightforward with standard T-bolts. Took off one star because the instructions were just a small diagram, but easy to figure out anyway.

Perfect fit for my 4040 workbench

These brackets are incredibly sturdy. I used them to reinforce the corners of my new assembly table, and they fit the 4040 profiles perfectly without any gaps. The black finish looks professional too.

Sturdy and reliable

Exactly what I needed for my shelving unit. The carbon steel feels much stronger than the aluminum-only brackets I tried before. Highly recommend for heavy-duty applications.

5 FAQ

Q: Are these compatible with both 20mm and 40mm profile slots?

A: Absolutely. These brackets are designed with universal mounting holes that accommodate 2020, 3030, and 4040 series profiles adhering to both National and European standards.

Q: Do these brackets come with the necessary T-nuts and bolts?

A: Yes, each package includes 4 brackets along with 16 T-nuts and 16 hex bolts required for immediate installation.

Q: What is the maximum weight capacity for a single corner connection?

A: While dependent on the specific frame design and bolt torque, a single bracket is generally rated to support up to 75kg, meaning a pair can handle approximately 150kg safely.

Q: Is the black coating durable enough for outdoor use?

A: The black oxide finish provides good corrosion resistance for indoor industrial environments. For prolonged outdoor exposure, we recommend applying an additional clear sealant or paint.

Q: Can I return these if they don't fit my non-standard profiles?

A: Yes, we offer a 30-day return policy for unused items in original packaging. Please ensure the brackets have not been installed or scratched before returning.
