ABSTRACT:
A spider for a railroad crossing signal foundation has plastic lined tubular channels extending through it with conical entry sections. In assembling a foundation, upright guide rods are guided into the channels by the entry sections without dislodging the plastic liners. In producing the spider, concrete is poured into a mold about tubular plastic liners so as to form entry sections and channels and to fix the plastic liners in the concrete to line the channels.
