I ordered the MT powder coated ones. I think the shipping inventory slip said OPOR on it. I think in the past they had 2 designs, but now the same design with powder coating being the difference (and consequently, higher cost of shipping to protect the powdercoat). [Someone correct me if I’m wrong]
Manhattan’s sliders appear to be one of the older designs, and not currently manufactured.
