Strong, Light and Easy to use

Size: 4pcs Black 3678 for 4040Verified Purchase

Highly recommend these. I used them for a roof rack build on my van. They’re light weight but very strong and well built. I plan on buying more when I add more crops beans to my roof rack for solar. Great product. Took me awhile to find these on Amazon.

Sturdy brackets with very sharp edges and terrible bolts

Reviewed in the United States on January 31, 2023

Size: 4pcs 7878 for 2020Verified Purchase

I bought 8 packs of 4 of the 78x78mm brackets. They arrived undamaged and very well-packed. The brackets are solid and heavy duty. These could have easily been 5 star brackets except for two problems. First, the edges on the brackets I received were crazy sharp. Initial handling of the first pack I opened left me with two fingers that had slices which felt like paper cuts. At that point, I realized that I was going to need to dull or chamfer every edge of all 32 brackets with a file or sandpaper before I could even use them. After a couple hours of tediously sanding every edge of all 32 brackets, I started installing them to reinforce the frame I had constructed using aluminum extrusions.
When I started mounting the brackets to the extrusions using the included bolts, I couldn't get the hex key to turn the first bolt. Looking more carefully, I noticed that the hex socket on the head of the bolt was too shallow to insert a hex key. The socket was only about 0.25 mm deep. It was more like a line outline of where the socket was supposed to be, instead of a hole for inserting a tool. I tossed that bolt in the trash and grabbed another from the bag of bolts which came with the brackets. The hex socket on that one was too shallow, just like the first one. The third one I tried actually had a usable hex socket on the top of the bolt. So, it went back and forth like this between good bolts and trash bolts without sockets through the entire installation of the 32 brackets. Overall, it turned out to be about 1/4 of all the bolts which weren't usable. I've never seen this many faulty bolts in one purchase before. Quality control must have been on vacation at the bolt manufacturer. Luckily for me, I have cabinets full of hardware to pull from when I don't get enough usable bolts in something I'm building.
It's a shame the edges were too sharp and a quarter of the bolts were unusable. The brackets would have been perfect without these two problems.

My mobile home screen door broke the plastic corners and these were a perfect replacement and saved the cost of a new door.

Great product - extremely solid and well built

Reviewed in the United States on October 25, 2021

Verified Purchase

The product (7878 version) is exactly as described. Incredibly solid - actually the most solid 2020 bracket I’ve ever come across.

Update: also ordered the 3750 version for 2040 profiles. Like the other product, once again very solid. Would recommend, though I wish the prices (currently $19/ 4pack) were a bit lower as I’d like to order about 8 more sets of 4, but would put the project over budget.

These work very well for assembling a frame with T extrusion.

Reviewed in the United States on January 9, 2022

Size: 20pcs 2028 for 2020Verified Purchase

You don’t have to slide the nuts in before you assemble, but it’s a bit tricky to get the nut turned 90 degrees and locked in. With that said, it would definitely be more frustrating to have to disassemble because you forgot to slide in a nut, than using this product.

Preis-Leistung nicht angemessen

Reviewed in Germany on April 8, 2022

Size: 4pcs 7878 for 2020Verified Purchase

Bestellt zum Versteifen eines 3D Druckers. Hält fest und sicher. Pro „Set“ war bei mir eine Schraube und eine Nut mehr dein als benötigt. Braucht man auch. Die Schrauben sind mutmaßlich günstige aus China. Der mitgelieferte Schrauenschlüssel analog. Für beste Ergebnis ein eigenes hochwertiges Bit benutzen und/oder eigene Schrauben (wenn man den fester anziehen will). Die Winkel ansich sind ok, allerdings sehr günstig verarbeitet. Die Kanten sind zwar so entgratet das man sich nicht schneidet, sehen aber aus sls hätte der Azubis selbst die Kanten einzeln mit der Feile bearbeitet. Alles in allem erfüllt seinen Zweck aber Preis Leistung nicht angemessen.
