ABSTRACT:
A roller type material rack comprises a base frame, two receiving mounts, and two rollers. The rollers are pivoted respectively to the receiving mounts for holding the material. The receiving mounts are pivoted symmetrically to the base frame such that the receiving mounts can be located at a predetermined position. The receiving mounts can be therefore adjusted to hold the materials having various shapes and sizes.
