This kit had everything you need and then some. I've only hung a 32" tv on it in the kitchen but I think it will hold up a lot more and I wish I had found this brand before hanging my 65" tv in the living room. It seems very solid, rotates and extends/retracts smoothly. The only thing I can think of to improve is the cable routing on the articulated arm.
