Might be, might not be. Sunex made those tools carts for several tool truck brands. Not counting the top box sitting on it, it could be a SP8225A with two drawer units SP82253D attached to it.
It's not a bad cart but, because it's relatively narrow at about 17 inches, I've seen them tip over pretty easy if you open both drawers with some weight in them. The Sunex platform cart was pretty popular before the new series of carts appeared. You can get a side shelf, screwdriver storage, and other accessories too.
