Very few SD45s had winterization hatches. I believe that only BN, CNW and WC had them. So for those modelers, stainless steel replacement winterization hatch screens are available for the Proto2000 models. Each package contains two (2) screens and two (2) sets of lift lugs. Refer to your prototypes photos to match up lugs. The center lugs on the fret can be used to replace the lift lugs on the rear corners of the SD45s roof. The first photo show the parts as packaged and the second photo shows a screen installed on a model.
