These things are HEAVY. The hardware is easy to identify, all looked of excellent quality,  and allows for fairly easy installation, adding individual pieces as you go so you aren't trying to hang 100# of steel in one pass. Once installed they are rock solid. As many have said, the worst part is jumping thru the instructions to various sections depending on how you are installing them. But this is truly minor if you take some time beforehand to 'walk' thru your install.

My only problem on the install was house construction related. These mount based on 16" or 24" studs (nice that both are supported!) However, the framers in my garage seemed to pay by the TLAR method (that looks about right) as the studs were off significantly. I remedied by mounting a ledger board to the studs, then the back frame to the ledger.
