2020 Aluminum Extrusion Connector Bracket Set Included 8PCS Joint Plates,1Pcs M3 Wrench,40Pcs M5 T-Slot Nuts and 40Pcs M5x8mm Screws for 2020 Series Aluminum Profile 3D Printer Frame

This was used on a project where 8020 extruded aluminum T-slot structures were used to build a stand. These T plates were used to join legs together for a stand. There are other methods to join struded members at a right angle, but this joint is super strong, yet lightweight.I have used these T plates before and they are easy to assemble. Because of the gusset plate design, this joint is stronger than other methods. I have used them in the past and will use them again in a similar application requiring a strong joint.

very good

The media could not be loaded. I think the kit is great. To do the whole printer however you need two sets I didn't realize or think about that. I think the quality is fantastic it came with plenty of screws and t nuts. For those who complain that it's missing screws and t-nuts, if you tap the holes on the ends of the extrusions, you don't use t-nuts. I ended up with extras in the end. I haven't had any issues as of yet, with the t-nuts breaking. I didn't go crazy over tightening them. I bought the kit twice not because I thought it was great but because I didn't realize I needed more pieces however I believe the kit turned out to be great and I'm glad I purchased it. I admit there is definitely a flat side of these brackets. I put the flat side towards the frame. The front edges are slightly rounded more so so I let them face outwards. No sharp edges.

The fit and finish is good it's obvious what they are designed for and now it's my preferred method

Unfortunately they look a bit weird on my all anodized project. Other than being painted they work fine.

Good quality and economical. These worked great for my 2040 extrusions.

Sturdy and thoughtful package. Comes with everything you need to get the job done.

compared to other brands I bought previously, this brand has the best quality. No sharp corners, they are all well deburred. all the holes are also nice and clean for screws. It also has nice texture that could help grip better.
