The second moment frame was also preassembled on the ground and was bolted to the double king studs at the right side of the operable window (I doubled the existing single king stud in the wall to create a post). It had a single horizontal piece that would form the near edge of the intermediate landing. It had a handrail post connected to the end of the horizontal piece and a second handrail post connected in the middle that ran down to the angle brace for rigidity.
The third moment frame was the identical to the second unit except it lacked the middle post. Being located at the building corner came with the added benefit that a metal strap could be run along the back side of the top horizontal member to overlap and nail to the rear wall. Since the vertical members of the second and third moment frames did not run down to the bottom of the wall to butt against the interior wall’s bottom plate like the first moment frame did (I could have done that but didn't think of it until it was too late), I installed a 2x4 band at the lower end of the vertical piece to help dissipate the inward force evenly across a greater section of the wall length and serve as base unto where I rest the lower end of the moment frame while I worked to connect it to the wall.
