Claim:
A method of assembling first and second frames, which represent door frames and/or window frames, to each other, the method comprising: (a) defining a first frame comprising a first plurality of jamb elements, connected to each other, at least one of the first plurality of jamb elements on the first frame having a first outer surface, a first nosing being included on the respective at least one of the first plurality of jamb elements at the outer surface of the respective at least one of the first plurality of jamb elements, the first nosing comprising (i) a first inner flange, (ii) a first outer flange, spaced from the first inner flange, (iii) a first outer-facing web connecting to the first inner flange and to the first outer flange, (iv) a first inner-facing web connecting to the first inner flange and to the first outer flange, and (v) a first receptacle having a first opening, a first remote wall of the first receptacle defining, at least in part, a first insert; (b) defining a second frame comprising a second plurality of jamb elements, connected to each other, at least one of the second plurality of jamb elements on the second frame having a second outer surface, a second nosing being included on the respective at least one of the second plurality of jamb elements at the outer surface of the respective at least one of the second plurality of jamb elements, the second nosing comprising (i) a second inner flange, (ii) a second outer flange, spaced from the second inner flange, (iii) a second outer-facing web connecting to the second inner flange and to the second outer flange, (iv) a second inner-facing web connecting to the second inner flange and to the second outer flange, and (v) a second receptacle having a second opening, a second remote wall of the second receptacle defining, at least in part, a second insert, one of the first and second receptacles extending from the respective first or second opening, into the respective nosing, the other one of the first and second receptacles extending from the other respective first or second opening into the respective other one of the first or second nosings; (c) bringing the first and second frames together in such alignment that the first remote wall is proximate and generally aligned with the opening in the second receptacle and the second remote wall is proximate and generally aligned with the opening in the first receptacle; and (d) moving the first frame relative to the second frame such that the first insert enters the second receptacle and the second insert enters the first receptacle and wherein the first and second remote walls are facilitating at least temporarily assembling the first and second nosings, and correspondingly the first and second frames, to each other.
