It is durably constructed of rolled steel filler, steel rail heel riser, cast iron toe and heel blocks, and heat-treated bolts applied with driving fit in the holes. It is furnished with extended points and a 45 degree bevel on the wing rails. This frog is recommended for heavy duty yard use and medium speed turnouts.
