🔧 Enhanced Aluminum Straight Connector Extrusion by PZRT: Boost Your Project Efficiency Review

I ordered these brackets to connect 3030 series extrusions to 8020 extrusions They fit well in the slots and look strong enough. My concern is that the screws that come with the brackets are a bit shorter. The packaging could also be improved. The plastic bag wasn't strong enough to hold those heavy clips.

Parts are bent, who has ever drilled them either with a blunt drill or the drilling feed was too high. Wavy due to the pressure with which they are drilled. They don't fit the 20mm x 20mm aluminum profiles I have. They are too thick and I have to file them down to make them fit. Also, the holes are not cleaned prior to tapping, leaving a raised ridge around the set screw holes. I wouldn't buy them again.

All 4 bolts are bent at the threading point. The aluminum has also been stretched due to the threads to prevent the bars from slipping in without pre-roughing all the bolt holes. I also had to file the burrs in the threaded holes. Very poorly built and nowhere near the photos shown in the description. The photos look very good but I can tell you this is not what I received. No wonder, because that is typical for Chinese products. After doing all the rework, the part worked the way I needed it…
