LAY OUT THE BUILDING SITE
After the site is prepared, lay out the building site.
Taking these steps
before
assembling the shelter saves
time and ensures that the structure is positioned as
desired.
Ground posts must be driven to the proper depth. Width of
the shelter is measured from the center of one ground post
to the center of the remaining ground post.
SQUARE THE SITE
Gather the parts:
• Auger ground posts (#103297)
• V-connectors (#103296)
• 5/16" x 2-1/2" machine bolts and 5/16" nuts
• End Clamp (#102857)
• Customer-supplied post hole digger (if needed)
1. Attach a V-connector to each auger ground post using
a 5/16" x 2-1/2" machine bolt and 5/16" nut.
3. After the first corner post is in place, string a line the
width of the first bay section (26' center-to-center) and
drill the second corner post into the ground just enough
to hold it in place.
4. Use a transit or line level to drill the second corner post
to the same depth as the first corner post.
5. String a line at least as long as the building from the
first ground post 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.
6. After squaring the position of the building, measure the
length and drill the next corner post.
7. Repeat the same step for the last corner post.
NOTE:
The distance measured diagonally between
corner ground posts must be equal for the building to
be square.
8. Check all dimensions (and adjust if needed) before
drilling the remaining posts to the required height.
9. After all four corner posts are accurately installed, tie a
string line between the tops of the corner ground posts
on the same side of the shelter. The string is used to
identify the tops of all side ground posts. The string
must remain tight and level.
10. Use a tape measure to mark the 72" on-center
locations of the remaining ground posts.
11. Drill the side ground posts into the ground at the
required 72" on-center width and the height identified
by the string.
NOTE:
Verify that the holes in the ground posts are in
the proper position and that each post is plumb and at
the correct depth.
2. Identify a corner where a ground post will be positioned
and drill the first corner auger ground post into the
ground using the "V" as handles. Use a post hole
digger if needed.
NOTE:
The top of the auger ground post will be one (1)
foot above the finished grade when properly driven.

Position the post with the
"V" handles parallel to
the front and back of the
shelter. The "V" section of
the posts will aligned with
the rafters.
Use the lower hole in
the V-connector and the
upper hole in the auger
ground post to connect
with the nut and bolt.
