Rough opening – An opening built into a framed wall, to accommodate the installation of a window or door unit. Also the vertical and horizontal dimension of that opening. The framing members, of a rough opening, are arranged to maintain the load bearing characteristics of the wall, without transferring any of the load onto the window or door units installed therein. Rough openings are framed slightly larger than the outside jamb dimensions of the specified window or door unit, to allow for leveling and squaring of the unit.
