ABSTRACT:
A threshold system includes modular plastic substrate sections of predetermined lengths that are attachable together end-to-end in a number of configurations to form substrates of various total lengths. A threshold assembly of a desired length is assembled by attaching selected substrate sections together to form a support substrate having a length corresponding to the sums of the lengths of the substrate sections, mounting an extruded aluminum sill to the support substrate, and mounting a threshold cap in the upwardly open channel formed by the attached substrate sections and the sill. A nosing strip may be secured along the inside of the finished threshold to cover the intersections between joined substrate sections and to provide an aesthetically pleasing appearance from the inside of a building in which the threshold is installed.
