About this item

  • Hight Quality Material - Inside corner brackets are made of premium quality aluminum alloy materials, which is strong and durable, anti-rust and anti-corrosion. The alloy material ensures that there is no magnetism and protects the matrix from corrosion; it has better heat shrinkage, hardness and stability.
  • Wide Applications - Corner braces are widely used in building industrial aluminum frame structures, electricity, shipping, furniture, construction and outdoor facilities, such as 3D printers, CNC routers, CNC laser cutters, CNC plasma cutters, robotics projects, 3D carvers, machine guards, tables, chairs, bed frames, racks, cabinets, guardrails, shelves, etc..
  • Function - A set of right-angle brackets for aluminum profiles, include 4pcs brackets, can be used for many projects, widely used to connection, reinforcement and support the right-angle corners of doors, windows, furniture, etc.. Please see the second picture for details size.
  • Easy to Install - Corner bracket is used as the connecting piece of aluminum alloy door, door leaf and outer frame. It can make the two pieces of furniture more smooth and confine through a 90 degree right angle.

These brackets are ok for what they are. It is hard to make too many criticisms of them other than they have unfinished edges. They don't appear to be sharp enough to cut easily, but I'll probably take some low grit sandpaper to the corners or maybe a deburring tool.

I ordered these to help piece together some components of my sim racing rig, and while they are totally useable, I was a bit disappointed with the quality. The edges are rough, with some being sharp enough to cause some nasty cuts, requiring me to bust out the file just to make sure no one snags on one of them accidentally. And while looks aren't everything, you can see a lot of discoloration that I don't see on any of the other stuff I use for aluminum extrusion.That all said, these are pretty strong, and definitely helped with rigidity for mounting my e-brake. If you are ok with some less-than-perfect manufacturing, these will get the job done just fine, but bear in mind there is no included hardware.

great little aluminum brackets. They are strong for aluminum. however if you are using them for more heavy duty purposes you may want o go with a steel bracket.

These will work fine for many projects. But, if you are building something precise you should buy better brackets than these. For my project, they were just good enough.

Poor QC or the extrusion is bad. These are getting returned. Not even close to 90 when held in a machinist square.

I would not trust these to support anything that I care about. I tried to shape & bend them to 90, but they are so drastically warped in and around the screw holes. Now I need a new file and physical therapy for all the extra effort. I am ashamed to admit that I took the bait and purchased these, to be honest. I would not recommend.

These were not even square, the extrusions are warped even over this short length and the edges were very rough. Not recommended.

If you are building something that needs a square corner with superior strength, then these are the way to go. I used them for a CNC machine enclosure that also supports overhead dust collection hose. I needed support for both corner and downward pressure and weight. These perform very very well.
