BEFORE YOU BEGIN...

Your Commander™ / Mountaineer™ Shed has a Modular Design.
This means your shed can be 
extended to virtually any length with 
the addition of Extension Modules. Extension 
Modules can be installed when you fi rst construct your 
building, or they can be added to it later.
How your building was shipped.
How you assemble your building will depend upon how many 
Extension Modules you have purchased. See below to see 
how many Modules are included in your building.

Now that you have received your building you need to take inventory of 
what you have to ensure nothing is missing. 
Depending on the size building you purchased, your building arrived 
in two or more cartons. Locate the carton label; you should have 
one carton labeled C1GA-A and one labeled C2GA-A. Also, if you 
purchased a building 15’ (4,6 m) in length or longer, you should have at 
least one carton labeled GA5M-A.

Please note: Most illustrations in this assembly manual depict a 10’x10’ 
(3,0 m x 3,1 m) building. A 10’x10’ (3,0 m x 3,1 m) building contains a 
front and rear wall section and one truss section (see page 9). Each 
additional Extension Module simply adds one more truss section to the 
building (see page 11). Every truss section is identical to every other 
truss section and the instructions clearly indicate how to assemble any 
length building. Read all instructions carefully.
This carton contains the painted parts needed to erect 
a 10’ (3,1 m) building. You should have one C1GA-A 
carton.
This carton contains the un-painted parts needed 
to erect a 10’ (3,1 m) building. You should have one 
C2GA-A carton.
This carton contains the Extension Module. Review 
the chart to the right to determine how many GA5M-A 
cartons you should have received.
