ASSEMBLE AND POSITION MAIN FRAME BASE RAILS
NOTE
: Assistance is recommended.
Gather the parts:
• Square tubing (See chart below)
• 1.75" x 1.75" square tube insert (#104075)
1-Way square tube fittings (#104624)
• Tek screws and nut setter 3/8'' x 2-9/16" magnetic
The base rails (main center section) consist of
2" x 2"
square tubing
and run the length of the building. The tubing
is connected by a 16" square tube (1.75" x 1.75") insert.
Each frame length has a different configuration of
2" x 2"
square tubes
. Listed below are the shelter lengths and the
needed tubing for one (1) base rail.
LAY OUT THE BUILDING SITE
After the site is prepared, determine where the building will
be situated and identify the location of the frame corners to
help square the frame after it is assembled.
Taking these steps before assembly 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 use, and the
method used to anchor the shelter.
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.
Shelter Length Tubing Requirement
20' 1 @ 124" & 1 @ 122"
24' 2 @ 124" & 1 @ 46"
28' 2 @ 124" & 1 @ 94"
40' 2 @ 124" & 120" & 118"
44' 4 @ 124" & 1 @ 38"
ASSEMBLE MAIN FRAME BASE RAILS
1. Locate your shelter in the table above and determine
the required tubing for the two main frame base rails.
Example: For a shelter that is 20' long, one base rail
requires one 124" tube and one 122" tube.
2. At each splice, insert the 1.75" x 1.75" square tube 8"
into one of the
2" x 2" tubes
and secure with two Tek
screws.
3. Slide the remaining
2" x 2" tube
onto the exposed
portion of the insert and secure with Tek screws. See
diagram below.

4. Repeat the steps for all base rail splices (if present)
and for the remaining base rail.
