20 Pack 1" Aluminum Corner Square Tubing Connector, 3 Way Square Tube Joints, 90 Degree Handrail Guardrail End Rails Clamps Chain Link Fence Fitting, Right Angle Structural Bracket

Great product, these are exactly as shown/described, and it's not the sellers fault the buyer doesn't read. They come as shown, without pre drilled holes. The price is a bit cheaper than what I can find locally so I will continue to source here whenever I need, thank you

Arrived as expected, good quality product for the purpose.

Ok product but there is no way to secure or keep the item in place. Unless you 1-Drill 6 holes on each connector. 2- Drill 2 hole on each end of the square tubing. 3- You need to got to the hardware store to buy 3 bolts, 3 flat washers 3 lock washers 3 nuts for every connector. Lots of work n time consuming

very poor quality parts. the insides are rough and some still have a thin sheet of metal blocking the opening

There are several aspects of these corners that may affect your intended use. First, there is an internal lip that stops 1” square tubing from going into the corner more than 7/8”. (This may be desirable for some fence uses. I don’t know. It wasn’t desirable for my intended use.) Second, they are very roughly finished and many will require additional sanding and/or grinding to use without cutting your hands. That said, they are sturdy and pretty much as advertised. The 1” internal dimension seems to spec in the few I measured. I’ll add comments in a few weeks if the 1” is out of spec on any.

Don't think there is any quality control. Some of connectors worked so make my own go no go gauge and will try to alter the rest to work. Part would fit in one end and same part would not fit other end.
