It's okay to house a dwarf in a Barney Cage, I'm not exactly sure but most Skyline Cages have 7 mm wires. I housed Toria (Dwarf Hybrid) in an Speedy Gonzales Cage before, I haven't seen her try to squeeze through so I suppose the Barney Cage will be a good cage.
Just something to watch out for is the height as they might climb and fall, though you shouldn't worry that much if your Hamster doesn't climb a lot.
