Abstract: A packaging block for cylindrical articles includes first and second identical L-shaped members adapted to be secured around the cylindrical article. Each member is formed with first and second substantially perpendicular legs having a semi-circular concavity formed in the interior contiguous surfaces of the legs. A boss is formed at one end of the first leg and extends outward therefrom. A correspondingly shaped groove is formed at the end of the other leg and extends substantially parallel to the boss. The first and second members are adapted to be disposed in an opposed, inverted manner around the cylindrical article with respective bosses urged into the corresponding grooves of the opposed members to interconnect the first and second members around the cylindrical article. Bores formed in each of the first and second members receive interconnecting pins to align adjacent packaging blocks in rows and tiers to form a complete bundle.
