Exactly what I needed!
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.

Okay but not great
One of them broke and I had to redo the connection of my tubing.

Brittle So Beware and Use in Non Critical Applications.
It will hold parts together but it’s cast not milled so it’s brittle and has little lateral strength or toughness.

Think before buying
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
