STEP 7: INSTALLING FRONT BASE RAILS AND VERTICALS
GARAGE DOORS: THE BASIC GARAGE BUILDING COMES WITH 1 GARAGE (OR OVERHEAD) DOOR OPENING.
24’ AND 30’ WIDE BUILDINGS CAN ALSO HAVE AN OPTIONAL DOUBLE DOOR OPENING.
DOOR SIZES: 12’ Wide-9’ Door, 20’ Wide-16’ Door, 24’ Wide-16’ or (2) 9’ Doors, 30 Wide-16’ or (2) 9’ Doors
Find the illustration that matches your building size and door style. Join the Base Rail tubes and (L) or (U) connectors as
shown. The Base Rails are all 2” square tubes. See illustration for tube length.
Measure and mark the location for the base rails and anchor the L & U connectors with expansion bolts as you did the
side base rails. NOTE: Leave the nuts slightly loose so you can install the vertical tubes. Attach the end base rails to the
side base rail pins with Angle brackets as you did on the back base rail ends after the vertical tubes are installed.
The door openings should be 9’ wide or 16’ wide.
Assemble the Door Vertical Tubes (see drawing for parts and location). Attach a Flat Bracket at the top as shown and
stack the vertical Door Jamb tubes on the L-Connectors or U-Connectors as shown. Plumb the Door Jambs and attach
the top portion of the assembly to the rafter or peak. Note that the Flat Bracket should be on the inside of the building. Be
sure to leave a space between the Door Jambs of 9’ or 16’ to install the door header.
Assemble the Door Header components as listed in the illustration and fasten them to the Door Jambs with Angle
Brackets on the top of the header. The basic garage door header height is 7’ you may have chosen to install a taller door.
Set the height at the bottom of your door header at 7’ or the height of your chosen door.
Now, install the vertical Header Brace in the center above the Door Header with 2 Angle Brackets at the bottom and a
Flat Bracket at the top on the inside of the building. The brace should be plumb. You may find it easier to attach the
brackets to the header brace on the ground (see detail). (NOTE: If you are installing a taller door than 7’ you will need to
cut the Vertical Header Brace to fit your door height.
