BLCCLOY 20Pcs 2020 Aluminum Extrusion Black Corner Bracket T Slot Inside L Sh...

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 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.

smaller than I thought but good quality and make.

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

Perfect. Product is exactly as described.

Because they are painted, I had to run a M5 tap through every one before they would accept the set screws.

Kit had enough pieces to put together an enclosure for my laser with swinging door frame. I really like the low profile of these over regular corner brackets that sit outside of the 2020 rails.

Great product for custom rack building.
