ABSTRACT:
A two part molded plastic reel wherein the parts are alike, and each part comprises a flange and a part of the spool, said spool parts being axially telescoped together to complete the reel. Each spool part has an exterior semi-flexible tooth member thereon which engages with a complementary inner fixed tooth member on the other part, so that the two spool parts when shoved together form a complete double wall spool which cannot be separated thereafter.
