Ugh. This is a piece of junk. The assembly could be ok if the hardware wasn't awful. Their are cam bolts and cam locks. The cam locks are so cheap that when you tighten them they just shear off and break. I think about 10-15 broke on mine, which means the thing is barely setting in one piece and super wobbly. They said they'd send me more pieces, but I haven't received them yet and I'm sure they'll be the same trash. Also, there were supposed to be plastic inserts for some screws to screw into and grip, but mine was missing those from the manufacturer - think plastic drywall screw holders. So, without those, screws have a hole bigger than the screw and can't grip. So, my doors - one went in, and the other has nothing to screw in to. This is terrible quality, terrible QI, and should not be purchased.
