A system, device and method of framing an opening, such as a window, in a clad façade 12 structure to align the window units 22 to be positioned adjustably so that the exterior sight lines align the windows without custom fabrication of the clad façade. This allows irregular variations in the original building structure to be eliminated by a perfectly aligned façade. A frame 20 has wide flanges 40 to allow the defined inner box frame area 34 to be positioned and then the frame can be shimmed to that position. Sections of frame 20 are joined by an angled member 54 with flat portion which are received in slots 56 in frame sections at their edges.

An overhead door frame assembly has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar. One of the splice assemblies is fastened to each upright column. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders to move the overhead door to an open position and a closed position.

A double egress door frame has a channel-shaped header with upstanding sides connected by a central web. The central web has a first series of slots that are offset to one side of the central web and a second series of slots that are offset toward the opposite side of the central web. Door stops comprise a right elongated channel-shaped member and a left elongated channel-shaped member. The channel-shaped members are attached to the central web of the header by tabs extending from the sides of the channel-shaped members. The tabs engage the slots. Once the tabs have passed through the slots to the opposite side of the central web, the tabs are twisted thereby connecting the channel-shaped members to the central web. A spot weld is used to insure the door stops is permanently locked into position.

A frame system for retrofitting a door frame system to secure a cooperating security door. The frame is formed of two opposing frame units that are installed over a pre-existing door frame from to opposing sides. The frame units are sized such that one fits within the other and partially overlap where the two units meet. A cooperating security door is hung from one of the frame units.
