LOCATION

Choosing the proper location is an important step before

you begin to assemble the structure.

The following suggestions and precautions will help you

determine whether your selected location is the best

location.

• Never erect the structure under power lines.

• Identify whether underground cables and pipes are

present before preparing the site or anchoring the

structure.

• Location should be away from structures that could

cause snow to drift on or around the building.

• Do not position the high tunnel where large loads

such as snow and ice, large tree branches, or other

overhead obstacles could fall.

SITE

After choosing a location, proper preparation of the site is

essential. Follow the information below.

• A level site is required. The site must be level to

properly and safely erect and anchor the structure.

• For sites that are not concrete or gravel, placing wood

blocks or other suitable supports under each rafter leg

helps prevent the pipes from sinking or working into the

site.

• Drainage: Water draining off the structure and from

areas surrounding the site should drain away from the

site to prevent damage to the site, the structure, and

contents of the structure.

WARNING: The individuals assembling this structure

are responsible for designing and furnishing all

temporary bracing, shoring and support needed during

the assembly process. For safety reasons, those who

are not familiar with recognized construction methods

and techniques must seek the help of a qualified

contractor.

CUSTOMER-SUPPLIED MATERIALS — Baseboard, Ribbon Boards, & Wood Screws

Baseboards and ribbon boards are optional, but recommended, for buildings with roll-up sides. Materials for baseboards

and ribbon boards are not included and are supplied by customer.

ATTENTION: Fasteners to secure boards to

building frame are included. Recommended lumber

dimensions shown; wider boards can be used if

desired. Counter sink holes for 1/4" carriage bolts if

bolt length is too short for board thickness.

BASEBOARDS

The baseboard, when installed properly, helps prevent the

ground posts from sinking into the ground when anchored.

Depending on the building, it also provides a surface to

attach struts or other building components.

ATTENTION: Baseboards run the frame length along both

sides at ground level. Installation of customer-supplied

baseboard is described later in this guide.

RIBBON BOARDS

A ribbon board typically runs a few feet above the ground

along the sidewall. It serves as a mounting surface for the

u-channel that secures the main cover and roll-up portion of

the main cover.

MATERIAL DIMENSIONS

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:

• Ground Posts

• Ground Post Couplers

• 5/16" x 2-1/2" machine bolts (#FAG336B)

• 5/16" Nuts (#FALB02B)

1. Identify a corner where a ground post will be positioned

and drive the first ground post into the ground.

NOTE: Insert the ground post driver into the top of

the ground post to protect the post and drive the post

into the ground. The top of the post will be one (1) foot

above the finished grade when properly driven.

2. After the first corner ground post is in place, string a

line the width of the building (center-to-center) and

drive the second ground post into the ground just

enough to hold it in place.

3. Use a transit or line level to drive the second corner

post to the same depth as the first ground post.

4. String 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.

5. After squaring the position of the building, measure the

length and drive the next corner ground post.

6. Repeat the same step for the last corner post.

NOTE: The distance measured diagonally between

corner posts must be equal for the building to be

square.

7. Check all dimensions (and adjust if needed) before

driving the remaining posts to the required height.

8. After all 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 remaining ground posts. The

string must remain tight and level.

9. Use a tape measure to mark the 48" on-center

locations of the remaining ground posts.

10. Drive the remaining ground posts into the ground at the

required 48" 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

driven to the correct depth.

ATTENTION: Position the pre-drilled holes facing to the

inside/outside of the shelter so they can be aligned with

the bolt holes in the rafter legs.

To align the bolt holes in the ground posts with those

in the rafter after driving the ground posts, insert a

tapered rod or pry bar into a ground post bolt hole and

turn the post using the rod or pry bar.

ATTENTION: Install the screws so they will not touch

the cover once it is installed. This is typically on the

backside of the rafter, which will be the surface visible

from the inside of the high tunnel once the frame is

assembled.

4. Assemble rafters as described and continue with the

additional steps to complete the assembly of the two

(2) end rafters.

3. With the main rafter pipes seated at each joint and the

rafter positioned on a flat surface, secure each joint

with a single self-tapping Tek screw. Position Tek screw

approximately 2" from pipe joint.

END RAFTER ASSEMBLY

In addition to the steps in the previous procedure, complete

the following steps for the two (2) end rafters only.

1. Take one of the assembled rafters and place it on a flat

surface.

2. Slide five (5) end clamps (102857) onto the rafter in the

locations noted below. (Do not secure the clamps to the

rafter at this time. These clamps will be repositioned

during the frame assembly when the purlins are

added.)

NOTE: Position all clamps as shown. Use a piece of

duct tape (if desired) to keep each clamp from sliding

when the rafter is lifted into position.

View of the end rafter and clamps as shown from the

outside when the frame is assembled.

3. Repeat the same procedure for the final end rafter.

4. Continue with the Frame Assembly instructions that

follow.

5. Position one (1) cross connector (102547) near the top

of the interior rafter assembly.

6. With assistance, take one (1) swaged 75" purlin

sections (#131S075) and insert the plain end through

an end clamp on the end rafter. Next, insert the tapered

end through a cross connectors near the top of the

interior (or second) rafter as shown above.

Saddle the purlin pipe in the joint where the rafter pipes

are connected to keep purlins aligned during assembly.

7. Repeat the previous step to install a second purlin

section. See the above diagram for details.

8. Verify that both rafters are plumb and properly spaced

(4' on center).

9. Tighten the 102547 cross connectors on the interior

rafter and tighten the end clamps installed at the end

rafter to secure the first sections of purlin pipe.

NOTE: Do not allow the plain end of any purlin to

extend beyond the end of the end rafter. Align with the

center of the rafter for best results and to prevent cover

damage.

IMPORTANT: Brace

the first rafter in

position as needed to

keep it from moving.

Bracing is removed

after additional
