Fits 2020 Seris Aluminum profile very well. Tried others from Amazon, they all stuck and cannot be used. But this one works perfectly! Good job, the seller!

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.
