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.

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
