Has Evergreen Scale models discontinued H-beam and I-beam shapes above 3/8" ?
I can see mounting the KD 802 box between the flanges of a 1/2" I-beam, or maybe a slightly narrower H-beam, and have a couple I-beams on hand. Sacrificing the flanges on the opposite side will result, as no channel stock this big enough to do this seems to be available, either. I can see where a single-piece extension for an 802 box for long-car use would be feasible. Dave Engle
