ASSEMBLE AND POSITION BASE RAILS
NOTE
: Assistance is required to assemble the garage
frame.
Gather the parts:
• Square tubing (see chart below) and 1-way connector
(105088)
• Tek screws and magnetic nut setter (3/8'' x 2-9/16")
The base rails consist of 2" x 3" square tubing (plain and
swaged) and run the length of the building. Each shelter
length has a different configuration of 2" x 3" square tubes
for the base rails. The tubing requirements
for each base
rail
for the different shelter lengths are listed below.
Consult Side Profile Diagrams in the Quick Start Section.
Assemble Base Rails
1. Locate your shelter in the table above and determine
the required tubing for each base rail.
Example:
For a shelter that is 36' long, one base rail
requires three (3) 123" swaged tubes and one (1) 78"
plain tube.
2. Insert the swaged end of each tube into the plain end
of a tube until the entire base rail is assembled.
NOTE:
Use a hammer and wood block to lightly tap
and seat the tubes together.
3. Repeat the procedure as needed for the remaining
base rail.
4. Install one Tek screw at each splice on
each side
of the
rail to secure the two tubes.
Do not install the Tek screws on the top or bottom
surface of the base rail.

LAY OUT THE BUILDING SITE
After the site is prepared, marking the ground where the
shelter will be situated and identifying the location of
the shelter corners helps to square the frame after it is
assembled.
Taking these steps
before
assembling the shelter saves
time and ensures that the structure is positioned as
desired. The following procedure is a suggested method.
Its use depends on the size of the shelter, shelter
application, the footings, and the method used to anchor
the shelter.
This procedure may not be needed for shelters that include
a base rail. It can be used, however, as a guide when
positioning the frame on the site during assembly.
SQUARE THE SITE
1. Identify a corner where a building rafter or base rail
will be positioned, drive in a stake, and string a line the
exact width of the building and stake in place.
2. Sting a line at least as long as the building from the first
stake at 90°.
NOTE:
A transit can be used to ensure an accurate 90°
angle, or the 3-4-5 rule can be used. Refer to diagram.
Using multiples of 3-4-5 such as 6-8-10 or 12-16-20
helps to maintain an accurate 90° angle.
3. After squaring the position of the building and placing
a stake at all corners, string a line between the stakes
to mark the base of the building.
4. Continue with the base rail assembly procedures that
follow.
