ABSTRACT:
A rod assembly for mounting a roll of sheet material within its own box including a rod member with a cylindrical bearing and an enlarged diameter end-cap which collectively form a first component, and a second component collectively formed by a matching bearing and end-cap having an axial slot for removably receiving the rod member. After initial perforation of the panels at the end of the box by the rod member, the two components are insertable through and mounted in such end panels so that both bearings are journaled inside the open ends of the roll when the rod member is received in the axial slot. When the roll becomes empty, the two components can be manually pulled apart and reused by being compressed together into mounting engagement inside a full roll of material in another box.
