10Pcs Aluminum Extrusion 2020 Aluminum Profiles Corner Brackets with 20Pcs M5 T Slot Nuts and Bolts for T / V Slot Rail 2020 T-Slot Aluminum Rail

I love how easy and stable it was. I used it to add a seat to the rear of my golf cart. Worked great.

Fast, Just as described.

Super strong, nice 6mm bolts, easy to thread every time. These are the best 90 deg fitting that I have found. I'll use these and only these. These are the good ones for any 2020 project.

The corner idea is good but prongs would break off if there was any shifting while fitting or moving due to shearing. Luckily I was able to reuse the broken corner brackets for the door, with a bit of sanding smooth and painting. It would be great if they were made of something stronger. Fit very well w the tbar 2020s, however. The parts (set screws, hex wrench) were complete and very handy.Not recommended for anything that might need to be moved regularly.

While converting one of my old 3D printers into an enclosure, I decided to replace all of the plastic printed parts. I swapped out the corner triangles for these metal ones and it's far more solid now, no flex whatsoever. As an added benefit, they provide a small "shelf" at each corner to sit a platform on.

Used these to elongate my laser bed. Perfect fit and strong hold. No jumping or skipping when crossing the joint.

The twist lock fasteners were great and I could pop them in anywhere and not just from the end

From appearance these are very Heavy duty and perfect for multiple applications. Will buy more in future .
