Crutchfield Customer Review (What's this?)
I was able to install them during the construction of our home prior to the drywallers coming in. They are sturdy and made it easy for the drywallers to install the drywall and cut around the brackets. Only reason for the 4/5 stars is that the screws that were included in the packaging weren't the highest quality. I had a few instances where the screws broke as I was drilling them into the studs.
Pros: Heavy duty and easy install.
Cons: Low quality screws included in packaging. Recommend using your own screws.
