Element Fitness OB-20 Dumbbell Single Handle

As much as you can load. The handles will take 300+ lbs each.

As much as you can physically load them with plates. The weight capacity is not measured because you would never be able to get enough plates on the handles to worry.

Hi BrandonThe bar weights approximately 10lbs

Hello,The ends that you slide the plates on are roughly about 6 1/2".The number of plates that will fit depends on the weight increments you are planning on using.For example, this bar can hold two 45lbs plates and a collar per side or four 5lbs plates and a collar per side.It all depends on the size of the plates and the weight increments you will be using.

12lbs per handle
