the barthickness is 4mm, slighty undersized, I use 6 for my amazon, notised all measurements are given in inches except the bars diameter, and 4mm is about 1/6th of an inch, just thought I'd add that incase your not familiar with the metric system. However I must say the bars are quite thick for such a small cage tho. I would consider the cage to be an acceptable cage for a grey that doesnt really spend more time in it than sleeping and eating, or atleast dont have to spend any more time than that in it. however the opentop is looking the exact same way as the opentop one I got, and nah you don't use it unless you got something really locking it down. Anyways not entirely sure about is the thickness of the bars are enough or not, I actually think it should be enough, try a googlesearch what is recomended as the minimumdiameter of bars for a grey.
