A plastic post device for mailboxes includes a tubular member having a depression formed by a stem, a conduit having a recess formed by another stem. The recess of the conduit is aligned with the depression of the tubular member, and the stems of the tubular member and the conduit are engaged with each other, to laterally secure the conduit to the tubular member. The tubular member and the conduit each include an inner portion having a less specific weight than that of an outer peripheral covering which includes a ultraviolet absorber material and an anti-oxidation agent for protecting the post device from being rusted or damaged.
