ABSTRACT:
An improved fixture system for mounting a stair support truss to a module stair unit. U channel fixtures are secured to the collar and to the front base riser of a modular set of stairs. These fixtures are used to attach a truss support to the stair module; and, the truss support is itself modified to project upward a plurality of plane tenon supports so that they will engage U channel stair tread braces. In preparation for packaging and subsequent transportation, the collar and buttress fixtures are used as hard mounting points for bundles of the remaining stair support elements which are then banded thereto.
