Exactly as described

Fast shipping and the product matches the description perfectly. The 2020 series compatibility is accurate, and the finish is smooth with no sharp edges.

Solid industrial grade

Used these for a small CNC enclosure. They are robust and handle vibration well. I deducted one star only because the packaging was a bit loose, but the parts themselves were undamaged.

Perfect fit for my 3D printer upgrade

These brackets fit the 2020 profiles perfectly. The anodized finish matches my existing frame, and the included bolts were the correct length. Assembly was straightforward without any need for modifications.

Essential for DIY workbench

I used these to build a custom workstation frame using 3030 profiles. They hold the corners rigidly and the right-angle design makes squaring up the frame very easy. Highly recommended.

Good quality, slightly tight fit

The aluminum feels very sturdy and well-machined. One or two of the brackets were a bit tight going into the slot, but a gentle tap with a rubber mallet solved the issue. Great value for the price.

5 FAQ

Q: Can I use these with 3030 profiles if I only have 2020 brackets?

A: No, this specific kit is sized for the slot geometry of the profiles listed. We offer a separate SKU specifically designed for 3030 profiles which you can find in our store catalog.

Q: Is the silver finish prone to scratching during assembly?

A: The anodized finish provides good resistance to wear and scratching. However, we recommend using plastic-tipped tools or a soft cloth during assembly to maintain the aesthetic finish.

Q: Are these compatible with American Standard 2020 profiles?

A: These brackets are designed specifically for European/National Standard slots. While dimensions are similar, we recommend verifying your profile slot width (usually 6mm for Euro standard) before purchasing to ensure a snug fit.

Q: Do I need to drill holes in the aluminum profiles to use these?

A: No drilling is required. These brackets are designed to slide directly into the T-slot channel of your aluminum profiles and are secured using the included T-nuts and bolts.

Q: What is the tensile strength of the included bolts?

A: The included M5 bolts are made of Grade 8.8 steel, providing high tensile strength suitable for most industrial assembly applications involving aluminum framing.
