A: 24 pounds is the recommended maximum
A: Is states 24 lbs. in the specifications
A: Not sure of actual weight but I have hung some potted plants that are pretty heavy, especially after watering. They have to weight somewhere between 20-25 pounds and they are holding great.
A: It says 95 lbs but from all the bad reviews about the screw breaking off (and my own experience), I'm not sure I'd trust it.....
