Befenybay 20PCS L Model 90 Degree Interior Inside Corner Connector Joint Bracket with Screws for 6mm T Shape Aluminum Extrusion Profile 2020 Series

These are junk. The set screws are shorter than other brands. I’m unable to fully screw some of these down because the screw just continues spinning. Unclear if it is because they are so short or if it is because the cast bracket is such poor quality. The bracket itself is low quality — surface imperfections and burrs on the edges of the threaded set screw holes.I would have returned these if I had not waited two months to open them.

Poor quality. Tossed into storage container after receiving. Have used it as props and on scrap design.

Great fitment and function. Building several frames for computets and these are so much easier to work as oposed to the angle brackets with screws an nuts.

Their work great.

Cheap plated pot metal! They strip out and break fairly easily. They work to help keep a shape together but if you need a rigid connection with little flex this is not the answer.
