SAFETY PRECAUTIONS...
Safety precautions MUST be followed at all times throughout the construction of your building!
Care must be taken when handling various pieces
of your building since many contain sharp edges.
Please wear work gloves, eye protection and
long sleeves when assembling or performing any
maintenance on your building.
Practice caution with the tools being used in the
assembly of this building. Be especially familiar with
the operation of all power tools.
Keep children and pets away from the worksite
during construction and until the building is
completely assembled. This will help avoid
distractions and any accidents which may occur.
NEVER concentrate your weight on the roof of the
building. When using a step ladder make sure that
it is fully open and on even ground before climbing
on it.
Do NOT attempt to assemble your building on a
windy day. The large panels can catch the wind like
a “sail”, causing them to be whipped around making
construction diffi cult and unsafe.
Do NOT attempt to assemble your building before
double checking that you have all the parts indicated
in the parts lists (page 8) as well as all hardware
(page 7). Any building left partially assembled may
be seriously damaged by even light winds.
IMPORTANT NOTE ON ANCHORING
• Your building MUST be anchored to prevent wind
damage. An anchoring kit is not supplied with your
building and you have many options when it comes to
anchoring. See anchoring page for more info.
• You must also have a temporary anchoring system in
place in case you need to take a break from assembly.
See page 4 for more info.

ASSEMBLY TIPS &TOOLS
How to Select and Prepare Your Building Site: Before you start to assemble your
building, you will want to decide on a good location. The best location is a level area with good drainage.
• Allow enough working space so it is not diffi cult to move parts into position for assembly. Be sure there will be enough
space at the entrance for the doors to completely open. Also, there needs to be enough space outside the building to be
able to fasten the panel screws from the outside.
• Before assembling any parts, your base should be constructed and an anchoring system should be ready to use.
Watch the Weather Closely: Be sure the day you choose to install your building is dry and calm.
Do NOT attempt to assemble your building on a windy day. Be careful on wet or muddy ground.
Use Teamwork: Two or more people are required to assemble your building. One person can hold
the parts or panels in place while the other person fastens them together and handles the tools. This
makes the process of assembling your building faster and safer.
Tools and Materials: Here is a list of some basic tools and materials you will need to assemble
your building. Decide which method of anchoring and the type of base you will use to make a complete
list of the materials you will need.
• Work Gloves
• Safety Glasses
• Step Ladder
• No. 2 Phillips Screwdriver (Magnetic Tip Preferred)
• Utility Knife or Scissors
• Pliers
• Carpenter’s Level
• Tape Measure
• Power Drill (Cordless, Variable Speed)
• Nut Driver or Wrench
• Square
• String (for squaring the frame)
• Awl (to align holes)
• Lumber and/or Concrete
• Hammer and Nails
• Spade or Shovel
• Hand Saw or Power Saw

FREQUENTLY ASKED QUESTIONS
Q. How long will it take to assemble the building?
A. Assembly time depends on a variety of factors, including roof design, tools available, DIY skill and the pace
at which you work. Guidelines for each shed assembly are approximate AFTER completion of the base, and
assume two or more people working on the assembly. Generally, you should plan on at least one day working with
someone who can assist you; again, after constructing the base. Refer to the clock icons on each product page
on the website for specifi c time estimates.
Q. How do I decide where to put my shed?
A. The key to a successful assembly is to make sure the shed will be square and level when built. The shed can
be assembled directly onto level ground (grass or dirt). If you have location options, choose one that is already
fl at, with good drainage to control moisture. If you don’t have a fl at, well-drained area, you need to prepare the
space. Level the area using cinder blocks, concrete, crushed gravel or other sturdy materials. Once level with good
drainage, construct your base. Using a carpenter’s level, make sure your base is level and free of bumps or ridges
to provide good support for your building.
Q. What if I can’t fi nish my building in one session?
A. If weather conditions change so that it becomes windy or rainy, it is recommended that you stop assembly
until conditions improve. This is for your safety and for protection of the shed panels. However, do not leave
your unfi nished construction without fi rst temporarily anchoring the corners of the shed to your base and placing
weights, such as patio blocks or sandbags, on the fl oor frame. Failure to anchor the building if you leave it while
partially assembled could result in irreparable damage or personal injury if the building collapses.
Note: Most instruction manuals provide a warning note at the beginning of the installation step for corner panels,
stating that the remainder of the building assembly requires multiple hours and more than one person. Do not
continue beyond this point if you do not have enough time or help to complete the assembly that day. A partially
assembled building can be severely damaged by even light winds.
Q. Do I need to anchor my building?
A. Yes! Fully assembled buildings should be anchored using a permanent anchoring system. If you need to leave
your building before it is completely assembled, you will need to temporarily anchor the corners of the shed to your
base, and place weights, such as patio blocks or sandbags, on top of the fl oor frame.
Note: If you have to stop assembly for any reason before it is complete, do not leave your unfi nished construction
without fi rst temporarily anchoring the corners of the shed to your base and placing weights, such as patio blocks
or sandbags, on the fl oor frame.
Q. How do I temporarily anchor my building before it’s fully assembled?
A. An incomplete building must be anchored before breaking for any period of time to prevent possible damage.
•If the building is on a wood base, secure the frame with wood screws in the corners
•If the building is on a concrete base, temporarily anchor the frame in the corners
•Use patio blocks or sandbags on top of the fl oor frame as weights
•Secure the fl oor frame to the ground with ground augers or rope the frame in the corners to the ground

Q. What kind of base do I use?
A. You can:
•Use an Arrow Base Kit
•Pour a concrete slab
•Build a wood deck/fl oor (use exterior-grade plywood)
•Use patio blocks
•Build on crushed gravel, dirt or grass
Arrow provides a base kit accessory that is an option for most building sizes. If you are building a wood deck/fl oor,
an Arrow fl oor frame kit on top of your deck/fl oor assembles in minutes and provides a fl oor frame suitable for a
5/8” exterior-grade plywood fl oor (not included). A continuous unbroken plastic vapor barrier with a thickness of 6
mil. between the ground and the building’s base is also recommended.
Q. How should I measure for my base?
A. Shed dimensions are provided in “nominal” size. Nominal sizes are roof-edge measurements rounded to the
nearest foot and are not the measurements to use for constructing the shed base. So, carefully check the exact,
recommended base size in the specifi cations for your shed model.
Q. How do I align the holes in the wall panels with the holes in the fl oor frame?
A. Make sure that the shed is level and square, with the correct fl oor frame size, and that the corner panels are
installed correctly. Line up the large hole in the panel with the small holes in the fl oor frame. An awl can be used to
help align the holes.
Q. How do I align the holes in the roof panels with the holes in the roof beam and side wall angles?
A. Your building must be level and square in order for the holes to align. It must be square at both the top and
bottom. Check that the building is square by measuring diagonally. The two diagonal measurements will be equal.
If your building is out of square, carefully rock and push the shed until it is square. Also, try loosening the roof
beams to give more play and fl exibility. Non-alignment can also occur if your building is not level. You can raise
corners and shim under them to make it level. Check that the panels are installed in the proper location. The
building should not be permanently anchored until the complete unit is assembled; otherwise, you will not be able
to make adjustments for squareness during assembly. Do not attach the bottom of the roof panels to the side wall
angles until all the roof panels are up.
Note: If you have to stop assembly for any reason before it is complete, do not leave your unfi nished construction
without fi rst temporarily anchoring the corners of the shed to your base and placing weights, such as patio blocks
or sandbags, on the fl oor frame.
Q. How do I ensure that the sliding doors on the building will hang level?
A. Make sure that the door track has been correctly installed, with the long leg on top and the short leg on the
bottom. Check that the door slides are straddling the upper and lower legs of the door track assembly, putting the
door slide only halfway in the track. Also, the rounded end of the door slide should be at the bottom and the square
end at the top.
Q. What kind of customer support is available?
A. Our instruction manuals contain step-by-step assembly illustrations and guide you from preparation through
assembly to care and maintenance of your fi nished building. Each part is marked with a factory number for easy
identifi cation. In addition, our assembly animation (located under the Customer Support menu on the website)
provides helpful tips. But if you need to reach someone at Arrow, you can contact Arrow Customer Service, toll free,
at 1-800-851-1085 (press 1) or via e-mail at [email protected]. Have your model number and instruction
manual with you when you call.

Q. What if the rear wall angle and channels are too large to fi t inside of the rear wall panels?
A. Check the dimensions of wall assemblies. They should be slightly smaller than the fl oor frames. Lay the
assemblies on top of the rear fl oor frame and pull them up to the top of the wall panels causing the corner panels
to stand erect and not lean inward. Caution: Be careful to not scratch the panels on the way up.
Q. The wide rib always overlaps the crimped rib. Is there ever an exception?
A. This sequence is to be followed through the assembly process. However, this will typically happen once on the
rear and once on each side wall (vertical wall units only) where there will be either two crimped ribs overlapping or
two wide ribs overlapping. This may give it a tighter fi t, but it will work.
Q. Can the building be painted?
A. The buildings can be painted with an exterior-grade paint designed for use on steel. Contact your local paint
supplier for recommendations.
Q. I heard that rust might be an issue with steel; is it?
A. While steel can rust, with proper care this should not be an issue. For a long-lasting fi nish, periodically clean
the exterior surface and apply spray-on car wax. Touch up scratches as soon as you notice them by immediately
cleaning the area with a wire brush or emery paper, washing it and applying touch-up paint. This will minimize rust
and maintain your shed’s attractive appearance for years.
Q. How do I take care of dents in my shed?
A. Proper selection of shed size, including a suffi cient door-opening width, and proper placement of your shed
should minimize the possibility of damage. If a dent does occur, carefully push the dent out from the opposite side.
If the paint has been scratched or removed, touch up the area as soon as you notice it. Immediately clean the area
with a wire brush or emery paper, wash it and apply touch-up paint. This will minimize rust and maintain your shed’s
attractive appearance for years.
