SAFETY INSTRUCTIONS
Most injuries are caused by misuse and/or not following instructions. Use caution when using this shed.
To ensure safety, do not attempt to assemble this shed without following the instructions carefully. Check entire box
and inside all packing material for parts and/or additional instruction material. Before beginning assembly, read the
instructions and identify parts using the hardware identier and parts list in this document. Proper and complete
assembly, use and supervision are essential for proper orientation and to reduce the risk of accident or injury.
FAILURE TO FOLLOW THESE WARNINGS MAY RESULT IN SERIOUS
INJURY OR PROPERTY DAMAGE AND WILL VOID WARRANTY.
• Do not use or store hot objects such as grills, blowtorches, welding equipment, etc. in the shed.
• If using a ladder during assembly, use extreme caution.
• Two capable adults are required for shed assembly. (It is also recommended that a third adult function as an instruction reader.)
MODEL #6414
Sentinel
11’ x 3.5’ Outdoor Shed
Consult all local building codes, as well as city and county ordinances, to ensure
that the construction of the Outdoor Shed does not require a building permit. Proper
building permit documentation may be required in your neighborhood, and it would be
unfortunate to learn this after constructing the Shed.
Surface must be leveled before installation. We recommend building a level work
space with a cement or patio style surface. If the surface is not properly leveled, the
Outdoor shed will not assemble correctly. Proper surface leveling will save you time
in the long run, so please do not ignore this step.
Instruction #1016304 7/18/2006
Level Surface Notice:
Building Code Notice:
You may use a 1/2” phillips head screwdriver bit and a power screwdriver or drill,
instead of a hand screwdriver. However, be aware that the plastic pieces of your
shed can be damaged by overtightening of screws. To avoid damage we strongly
recommend the use of a low-powered power screwdriver or a drill that has an
adjustable clutch that is set on a low torque setting. If neither is available, use a hand
screwdriver. In any case use caution to avoid overtightening the screws.
Screwdriver Notice:
Sharp objects may damage your oor. If resting sharp, heavy objects on your shed
oor, place a block of wood between the sharp object and oor.

Dear Valued Customer,
We would like to congratulate you on your purchase of a Sentinel™ Outdoor Storage Shed! We
are condent that you have made the perfect choice and you will be very pleased with your new
storage solution.
Sentinel™ Outdoor Storage is part of the family of brands created and manufactured by
Lifetime® Products, Inc. Like all of our products, you can be assured that the quality of your
Lifetime Outdoor Storage Shed is the best in the world! All of our sheds are made in the USA,
something that is very important to us. And, we back that quality up by oering the best
warranty in the business – A 10-year warranty that fully covers the shed!
All of our sheds are built with the highest-quality steel and polyethylene parts. The design and
construction of our steel-reinforced double-wall panels is second to none. All of our exposed
steel parts and trusses are powder coated and we use high-impact polyethylene plastic. What
makes polyethylene so special? It has superior strength and durability, and, it won’t crack or
degrade outdoors.
So now that you know the quality you are geing in a Lifetime Outdoor Storage Shed, please
take the time to READ THIS INSTRUCTION MANUAL!
We have taken great care in providing the best possible form of instructions to help you put
your new Outdoor Storage Shed together. Before you get started, PLEASE read the following
preparation tips to help you get started!
We can assure you, your construction experience will be a lot more enjoyable if you do!
PREPARATION TIPS:
• The rst step is simple…RELAX! You have made a great purchase, but Rome was not
built in a day. Plan to spend a good part of your aernoon puing together your ne Outdoor
Storage Shed. Our philosophy is, if it comes together quickly and easily, it surely will come apart
quickly and easily! Your Lifetime Outdoor Storage Shed will surely last a long, long time, if you
are patient, and take all the time necessary to put it together as we have instructed.
• Grab a friend to join in on the fun! This is not a one-person endeavor. We have found that
not only will things go smoother if you have two or more people participating in the construc-
tion of the shed, but it will go quicker as well. So, the more the merrier!
• Make sure you have all the tools necessary for constructing your new shed. There is a
“Suggested Tools & Materials” list on page three of this Owner’s Manual.
IMPORTANT! Please Read

• The plastic pieces of your shed may become damaged by over tightening the screws. To
avoid this damage, we strongly recommend the use of a low-powered power screwdriver or a
drill that has an adjustable clutch that is set on a low-torque seing. If neither is available, use
a hand screwdriver. If a hand screwdriver is all you have, take several breaks…your wrist will
need it!
• You will also need two small step ladders (when it comes time to do the roof!).
• Before beginning assembly, remove the Parts List from the center of this Owner’s Manual
and take an inventory of the parts included with your Outdoor Storage Shed. Also, read through
the entire instruction manual. It’s always a great practice to get a feel for the ow of the process
and to familiarize yourself with the parts involved. But, try not to get ahead of yourself and start
the process out of order.
• FOLLOW THE INSTRUCTIONS IN ORDER! Everything goes together in a certain order,
and we have learned what that correct order should be. In our state-of-the-art research and test-
ing facility, we have painstakingly created these instructions. The order of construction is there
for a reason, and some parts simply will not t if built out of order. Just follow along with the
order in the instructions and everything will t together and things will go very smooth.
• YOUR SHED MUST BE BUILT ON A LEVEL SURFACE! If the spot you have chosen to
place your wonderful new Outdoor Storage Shed is not level, the shed will not assemble correct-
ly! We recommend a cement patio, a wood platform or creating a pad with pea gravel. Your shed
is meant to last a lifetime, so provide the proper foundation for it before you start to build.
• Before you build it, make sure you are allowed to build it! Consult all building codes, as
well as city and county ordinances, to ensure that you do not require a building permit to con-
struct your Outdoor Storage Shed. Proper building permit documentation may be required in
your neighborhood, and it would be quite unfortunate to learn this aer your Outdoor Storage
Shed is already built!
Now that you’re ready to begin the construction of your wonderful new Outdoor Storage Shed,
step back, take a deep breath, get yourself a large cold beverage and enjoy yourself. We guaran-
tee that aer spending the right amount of time in building your shed, you will be able to enjoy it
for years to come.
Thanks for choosing Sentinel™ Outdoor Storage, and have fun!

1Site Selection
The actual dimensions of your shed (at its widest and longest points) are 11’ x 3.5’. Be sure to select a site
that will accomodate these measurements. The base of the shed is slightly smaller than this, so you will
need to create a level surface that is at least 124” x 42”. We recommend using a level cement or patio style
surface. This will provide the best long-term performance for your shed.

Wherever possible you should use the surfaces described above. When this is not possible, we
recommend you use one of the following options:
Alternate Site Preparation

Now ll the inside of the frame with “Pea”
gravel. Use a leveling board to scrape off extra
ll material and to level the surface.
