Abstract: A reel for cable and the like has a tubular core portion having opposite open ends and a hollow interior formed with reinforcing ribs. A pair of end flanges is provided, each having a radially inner annular flange portion which is cupped so as to a have an open side facing axially inwardly of the core portion and which is, in part, received in one of the open ends, and a radially outer annular flange portion which is cupped so as to have an open side facing axially of the core portion and which has an outer circumferential edge face. Connecting portions connect the end flanges to the core portion.
