20Pcs 2020 Aluminum Extrusion Black Corner Bracket T Slot Inside L Shape Joint Angle Hardware Connector with Screws for 20 Series 20/20 2040 V Slot Extruded Aluminum Profile

These are nice quality and make a perfect 90 degree internal mounting bracket on 2020 extrusion. These seem sturdy enough for most applications of 2020 extrusion.

I'm thoroughly impressed by how well these held up in my project. I was demanding more than their allocated weight, and they hold up no problem.

Reasonable but variable quality. The tapped holes and the set screws both are inconsistent - some screws are too loose in some holes and too tight in others and vice versa. Still fine, for the price.

I bought these for the Ender 5 I own. It's still in pieces at the moment but these corner brackets work exactly as specified. They helped me make the entire printer more square than before my tinkering. The Y axis motion is smoother due to being more square. Absolutely a breeze to use. They sit inside the frame, so they are not unsightly like the original corner brackets. Remember to use thread lock on the grub screws.

Perfect. Product is exactly as described.

I can't decide between a 1 and a 5. So 3. These on first glance are a good buy. They work really well, and I was able to put together what I needed quickly. But they won't stay together. Every time I move the structure, one of them pops out. I pretty much have to torque it down enough to almost damage the allen wrench before it'll even have a fighting chance of staying screwed in. I really, really want to give it a 1... but if it weren't for that, they'd be great. So, 3.

Great product for custom rack building.

Works well will my 2020 aluminum. It is sturdy and reasonably priced

J aimerais savoir si il y a des équerres plus grandes mais qui a 6 mm la même mesure mais plus long de chaque cote

Es un buen producto y al empacarlo no se dañó.
