ABSTRACT:
A railing system for porches, decks, steps, ramps and the like having a top and bottom rail formed of wood containing a wood preservative that is corrosive to aluminum, aluminum alloys, paint and the like. The system has hollow metal balusters formed of metals which may be harmed by the corrosive effects of the wood preservative.

The connectors are also useful with untreated wood such as cedar or with synthetic materials.
