What size connector will go with this to make it into a barbell?

I would avoid adding any connector to these. The bars are plastic and too long. If you add a connector, it will surely break the dumbbell bars fast. However, it’s up to you. A standard 1 inch connector should work.

How much does the bar itself weigh?

Hi, the bar itself weight approximately 4 lbs.

HI, the item is missing star lock collars, so there is no way to use the weights?

i lost mystar lock collars is a way to get that item again ?
