Looks good
I bought these because I haul conduit and ladders on top of my jeep, I got an aftermarket rack for my jeep which utilizes T-slot extruded aluminum bars. Last week I was hauling 2" rigid metal conduit and when I released the straps it all rolled off and wiped out my mirrors. I got these to provide an edge. The rack is made by Goliath off-road, the jeep in a 1999 grand Cherokee.

Very Good Quality!
The quality of these extrusions was much better than expected. They appear to be black anodized. Used them to strengthen my Ender 3 and they did a great job! The t-nuts slide in so they don't turn which is a plus.

Strong and well made, but....
The bracket is strong and very well made, but it stated it came with 6mm hardware, but my box came with 5 mm screws and T nuts.

Very heavy duty corner brackets...
Working on a couple 2020 extrusion projects and parts like this are always handy. Never have enough parts, right? When I pulled these out, I was surprised just how heavy duty these are. They are beyond what I hoped or needed, but I am not complaining. Well made with a great fit and finish. Plus you get nuts and bolts, all you need. They might seem a tad pricey, but you do get what you pay for with this set.Very robust, okay price, would recommend.

My current go-to for strong interior connectors
When I need a strong connection and have space in the corner, these are my favorite reinforced corner support. They are straightforward to assemble and give additional torque support over simple 90 degree or interior connectors.
