The top part of (B2) hooking to C was broken out so screw socket would not tighten up.  Also had crack down part side B2 and scratch on front part of drawer facing.  Very disappointed in paying $271 for sub par work!  Very wiggle so had to use extra brackets to get it sturdy.  Had to secure to wall since it felt as if it would fall over.  Very disappointed in this item and I am regular customer.
