Owners should be very involved in the planning process. Hiring someone to. do it or delegating it to someone who is not a key member of the company. will result in an inferior plan. No plan (or a poor plan) is a leading cause of business failure. You can. improve your chances of success with a good Business Plan.
Instructions. Position the metal studs that will form the two sides of the rough opening so that the distance between them is 1 inch greater than the exterior dimensions of the door frame. This provides you with space to adjust the door frame and make it perfectly square and level with shims.
For a 6' 8 high door (80 inches) I like to frame my rough opening heighth at 82 3/4. This allows room for all the situations mentioned above. If your header material is a. double 2x12, holding it to the top plate will give you that heighth. Rough openings for door widths are pretty much standard. The rough opening width is 2 inches wider than the door itself. this allows room for the door jambs which are usually 3/4 thick. This gives you approximately 1/2 of play and shim room when installing a prehung door. For a 36 door (3' 0) the rough openig width would be 38.
