A railroad track insulator, part therefor and methods of making the same are provided, the railroad track insulator being adapted to hold a railroad rail against its foundation and comprising the combination of a metallic part and a polymeric part secured together so that the polymeric part is adapted to engage the rail. The metallic part has an open ended recess in one of the opposed sides thereof and is defined by a peripheral flange arrangement thereof. The polymeric part has a peripheral edge and is disposed and secured in the recess so as to have the peripheral edge thereof supported by the peripheral flange arrangement of the metallic part. The metallic part comprises a stamping that has a generally L-shaped cross-sectional configuration that defines two legs thereof being disposed at an angle relative to each other, each leg having opposed ends and an outer free end extending between the opposed ends thereof. Each end of each leg has a part of the peripheral flange arrangement bent therefrom and being spaced from adjacent parts of the peripheral flange arrangement.
