This unit is well constructed and pretty easy to install. But the long allen wrench supplied to tighten down the lock screws had an issue. The short end of the "L" shaped wrench was too long and will hit against the wall when you try to turn it. This made for a long and tiresum time trying to tighten the lock screws down one-half of a turn at a time. The handle end needs to be shorter or cut off for easier use. Other than that, the product was well constructed.
