How to Frame a Garage Door Opening
1. Frame the rough opening for the opening to 3 inches wider than the garage door you have selected.
2. Frame the rough opening to a height that is 1.5’’ taller than the door that you have selected.
3. To finish the opening cut the header and jambs from 2’’ lumber. Depending on your opening, the lumber width will be 6’’ to 8’’ wide. Use framing nails to attach the header and jambs.
4. To prepare for the garage Door Installation, you will need to follow these instructions, and pay special attention to the requirements laid out in the sketch below.
5. Pull a measurement from the floor of your garage to the ceiling next to the garage door opening. Cut two 2’’ x 6’’ pieces of lumber, and attach to the face of the wall running from the edge of your garage door jambs to the ceiling of your garage. This lumber will be used to attach your garage door track, and a portion of your assembly.
6. Next, pull a measurement between the 2’’x 6’’ lumber that you just attached to the face of the garage wall. Now, cut a 2’’x 6’’ piece of lumber to that measurement. Attach lumber to the face of the garage wall to the edge of the garage door header
7. Last, pull a measurement from the top of the 2’’ x 6’’ piece of lumber that you just installed to the ceiling of the garage. Cut a 2’’x 6’’ piece of lumber, and nail to the face of wall exactly in the center of the garage header. This piece of lumber will be used to attach the center bracket of your garage door spring assembly.
