Zeberoxyz 20PCS Black L-Shape Joint Corner Bracket,2020 Series 90 Degree Aluminum Profile Interior Joint-with M5 Screws,Suitable for 6mm Slot Aluminum Extrusion Profile (L Corner Bracket-Black)

Works Great & Great Price, I will buy again... I'm Happy!!!

Excellent product and service . Purchased the 90 degree connector for t slot .I left a bad review here by mistake for another seller and product a compressed air horn and 2 canisters the canisters never delivered with no recourse due to non Amazon fulfillment.My apologies.

I was using these t-nut for preprinted parts that matched the dimensions listed. The parts recieved would not fit and were useless for the intended purpose of this purchase. Dimensions matter. My experience with parts sold out of China are incorrect sied or have unacceptable tolerance for use in projects that requires even minimal precision. These parts are junk.

I have been stocking up on 2020 and 20XX extrusions, with some projects to build and this will be a great addition to the hardware stock. They are well made for what they are, good fit and finish. Set screws are tiny, but that is to be expected. I was lazy and only grabbed some 2040 rails and these connectors fit well. Wish they were a little tighter fit, but they work well.Good connectors, good price, would gladly recommend.

These are an easy what to build a box connecting three pieces at a time. You do have to brace them as you build, one bracket by itself is not very strong. But as a completed box it makes a solid structure. And the open ends have a nice finished look.

Like a metal you could bend with your teeth. Amost like ceramic inside. Not for anything structural and will warp and break.

The bracket was under sized. The set screws would not stay tights, maybe thread was off? Brackets seem to be brittle and made with something besides zinc allloy
