these instructions before you begin.
If you have any questions during the assembly, contact
Customer Service for assistance.
SAFETY PRECAUTIONS
• Wear eye protection.
• Wear head protection.
• Wear gloves when handling metal tubes.
• Use a portable GFCI (Ground Fault Circuit Interrupter)
when working with power tools and cords.
• Do not climb on the shelter or framing during or after
construction.
• Do not occupy the shelter during high winds,
tornadoes, or hurricanes.
• Provide adequate ventilation if the structure is
enclosed.
• Do not store hazardous materials in the shelter.
• Provide proper ingress and egress to prevent
entrapment.
ANCHORING INSTRUCTIONS
Prior to assembling this shelter, please read the anchoring
precautions and instructions included with the kit.
Anchoring instructions are included in the MUST READ
document. You must anchor the building after the frame is
assembled and before the cover is installed.
WARNING: The anchor assembly is an integral part
of the shelter construction. Improper anchoring may
cause shelter instability and failure of the structure.
Failing to anchor the shelter properly will void the
manufacturer’s warranty and may cause serious injury
and damage.
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 shelter 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. The following site characteristics will help ensure
the integrity of the structure.
• The support structure must be level to properly and
safely erect and anchor the frame.
• If the site is not level, use footing to provide a secure
base for the structure. Pre-cast concrete blocks,
pressure-treated wood posts, or poured footings are all
acceptable when properly used.
• 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.
ASSEMBLY NOTE: Install Tek screws using a
clutched drill driver running approximately 750 RPM
while applying approximately 50 lbs of force.
Do not use an impact driver!

LIST OF WORDS AND PHRASES
Before you begin, it is important to become familiar with the
words and phrases used in this instruction manual.
These words and phrases are common to most
ClearSpan™ shelters and identify the different parts of
the shelter. (Some are used in this document. Others may
not apply to this particular shelter.) These terms describe
the shipped parts and can also be found on the materials
list/spec sheets included with the shipment. To aid in the
assembly, read through the following definitions before you
begin to assemble your shelter.
• Conduit: An assembly of pipes used to secure the
main cover and end panels (if equipped). Purlins and
some strut assemblies also consist of connected pipes
to form a conduit. Each pipe joint of a conduit assembly
is secured with a self-tapping Tek screw.
• Coupler or Fitting: A part of the frame assembly
where legs, purlins and rafter pipes are inserted and
secured. In most instances, 3-Way and 4-Way couplers
are used. In some larger applications, couplers are
used to secure the joints of the different rafter sections
during the assembly of the rafters. Some shelters do
not use couplers.
• Base Plate: The part attached to and found at the base
of the rafter or leg of the shelter. Depending on the
shelter, the base plate is an optional purchase. Some
shelters do not offer an optional base plate; some use
1-Way connectors; others use ground posts.
• Must Read Document: This document includes
building and shelter anchoring instructions, steps for
end wall reinforcement, safety precautions, and notices
and warnings. The Must Read document is sent with all
shelters and buildings. If you did not receive a Must
Read document, contact Customer Service to request
one.
• On-Center: Term used to describe a measurement
taken from the vertical center of the rafter or frame
member to the vertical center of another.
• Purlin or Angled (or Lateral) Bracing: The pipe
assemblies that run perpendicular to the rafters
or framework that supports the main cover. These
assemblies are found on the sides and roof areas of
the assembled frame, are evenly spaced, and typically
run from the front to the back of the shelter.
• Plain or Straight Pipe: A term used to describe a pipe
that has the same diameter or width throughout its
entire length.
• Strut: A strut is usually a length of pipe with two
flattened ends and is used for diagonal bracing of the
shelter frame. A strut is typically secured to the frame
work by special brackets, bolts, and/or clamps.
• Swaged End or Swaged Pipe: The term "swaged''
refers to the tapered end of the pipe or tube. Swaged
ends of a pipe can be inserted into couplers and the
straight ends of other pipes of the same diameter.
• Tek Screw: A self-tapping fastener used to secure pipe
joints and to fasten brackets to rafters.

Free-Standing Building
OVERVIEW
This section describes assembling your free-standing
building. For details of each assembly procedure, consult
the Quick Start Guide and the individual sections of these
instructions. See illustration below to identify main parts of
shelter.
1. Layout the site and identify the required parts for each
assembly procedure.
2. Assemble all rafters.
3. Assemble and anchor the frame.
4. Prepare and install the main cover.
The instructions that follow describe assembling all rafters
and then constructing the frame. Depending on the number
of individuals assisting with the construction, it may be best
and more efficient to have someone assemble the rafters
and others assemble the frame as rafters are completed.
Other factors to consider during the assembly, especially
for buildings longer than 60', include:
• Amount of working area
• Available lifts and work platforms
• Number of assistants

LAY OUT THE BUILDING SITE
After the site is prepared, identify the location of the shelter
corners to help 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.
SQUARE THE SITE
1. Identify a corner where a building rafter will be
positioned, drive in a stake, and string a line the exact
width of the building and stake in place. (Width of the
rafter is measured from center-to-center of the rafter
legs.)
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. Next, paint or mark a line on the ground using the
strings between the stakes as guides.
NOTE: If boards are
used, drill holes through
them at evenly-spaced
intervals along the
length. Drive a rod
through each hole and
into the site to prevent
the boards from shifting
and to maintain the
on-center width of the
building.
Actual rafter is not shown.
Board
Rod or Ground
Stake
NOTE: Setting customer-supplied boards on the site in
the correct positions is another way to prepare for the
frame assembly.
The boards can be "pinned" in place using rods driven
into the site through evenly-spaced holes drilled in
the board. This prevents them from shifting during
assembly.
Building width is measured on-center.
5. After marking the outline of the building, continue with
the rafter assembly instructions.

ATTACH MAIN COVER (CONTINUED) SHELTER CARE AND MAINTENANCE
Proper care and maintenance of your shelter is important.
Check the following items periodically to properly maintain
your shelter.
• Regularly inspect the main cover and panels (if
equipped) to see that these remain tight and in proper
repair.
• Check the cable turnbuckles and cable clamps to see
that these remain tight. Tighten as needed. Check the
cable to verify that it is not worn, wearing on a frame
member, or touching the main cover or end panels (if
equipped). Some shelters do not use cables.
• Check connections and all fasteners to verify that they
remain tight.
• Do not climb or stand on the shelter at anytime.
• Remove debris and objects that accumulate on the
shelter. Use tools that will not damage the cover when
removing debris.
• Remove snow to prevent excess accumulation. Use
tools that will not damage the cover when removing
snow.
• Check the contents of the shelter to verify that
nothing is touching the cover, side panels, or the end
panels that could cause damage.
• Check the anchoring system to ensure that all
components are tight and in good repair.
• Review the MUST READ document for anchoring
requirements.
• Inspect all building components regularly. Replace all
worn or damaged parts promptly.
• If the shelter is disassembled and moved, inspect all
parts and connections before reassembling.
• For replacement or missing parts, call 1.800.245.9881
for assistance.
NOTE: With the exception of Truss Arch buildings,
ClearSpan™ shelters and greenhouses do not have any
