Review on 🚚 Harper Trucks: High-Capacity Flat-Free Wheels by Derek Dolla

The shape of the two crossbars is not clear from the archive photos. They appear to be bent, but I wasn't sure. Before ordering, I asked in the question section if they were curved or straight. I got four "wrong" answers (straight), then finally one correct answer (crooked). Curved crossbars help move objects. like trash can. so that the item does not roll sideways when moving. I bought it and am *very* happy with my purchase.
