20 Pack 1" Aluminum Square Tubing Connector, 3 Way Square Tube Corner Coupler Structural Chain Link Fence Rails Pipe Clamp

Product description accurate and exactly what I needed! Don’t understand what some of the reviews were for poor quality. Yea you had to knock off some leftover metal from the manufacturing but comes right off.

Bueno

Arrived as expected, good quality product for the purpose.

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.

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

It will hold parts together but it’s cast not milled so it’s brittle and has little lateral strength or toughness.

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.
