Fast shipping and great product

Arrived two days earlier than expected. The packaging was secure, and none of the small parts were lost. These connectors make the whole structure feel incredibly rigid. Will buy again for my next project.

Sturdy and reliable

I used these to build a shelving unit for my garage. They handle the weight of heavy storage bins without any flex or wobble. Great value for the price considering you get the nuts and bolts included.

Essential for 3D printer frames

Bought these to reinforce the corners of my custom 3D printer frame. The vertical angle design provides much better stability than standard flat plates. Highly recommended for precision builds.

Decent but threads were tight

The brackets themselves are solid, but I had to spend some time cleaning out the threads on two of them before the bolts would screw in smoothly. Once installed, they work fine.

Perfect fit for my workbench frame

These brackets are exactly what I needed to finish my aluminum profile workbench. The anodized finish matches the profiles perfectly, and the included hardware made assembly a breeze. Very sturdy once tightened.

Good quality, slight color variation

The build quality is excellent and they hold the frame together very well. There is a very slight difference in the silver shade compared to my existing profiles, but it's barely noticeable unless you look closely.

5 FAQ

Q: What size hex key do I need for installation?

A: You will need a standard 4mm hex key (Allen wrench) to tighten the bolts securely into the T-nuts within the profile slots.

Q: Does the package include the T-nuts and bolts?

A: Yes, each order includes 4 vertical angle brackets, along with 16 T-nuts and 16 M5 bolts sufficient for installing all four connectors.

Q: Can these be used outdoors?

A: While the anodized finish offers some corrosion resistance, these are primarily intended for indoor applications. Prolonged exposure to rain or harsh weather may eventually affect the finish.

Q: Are these compatible with 3030 aluminum profiles?

A: No, these specific brackets are designed exclusively for the 20 series (20x20mm) profiles. Using them with 3030 profiles will result in misaligned holes and an insecure fit.

Q: Is there a left-hand and right-hand version?

A: No, the vertical angle bracket is symmetrical in function regarding left or right orientation; it is designed to connect two profiles at a 90-degree vertical intersection universally.
