The Base For Your Building
OPTION 1: ARROW FLOOR FRAME KIT:
(Order No. FB109-A or 68385-A)
Arrow has the best base for your building in this simple kit. It keeps stored items above the ground.
This kit should be used with one of the following:
A. To support a plywood deck B. To be fi lled with sand. We recommend the combined use of
1. an ARROW FLOOR FRAME KIT and 2. an ARROW ANCHORING KIT as an effective method of securing the building to the
ground. Allow 1 - 2 hours for construction.
OPTION 2: Wood Platform
If you decide to build your own base, be sure to select the appropriate materials.
These are the recommended materials for your base:
 2 x 4's (38 mm x 89 mm) Pressure Treated Lumber
 5/8" (15,5 mm) 4 x 8 (1220 mm x 2440 mm) Plywood-exterior grade NOTE: Pressure Treated Lumber must not be used where
it will make contact with your storage building. The properties of Pressure Treated Lumber will cause accelerated corro-
sion.
If Pressure Treated Lumber comes in contact with your storage building your warranty will be voided.
 10 & 4 penny Galvanized Nails  Concrete Blocks (optional)
The platform should be level and fl at (free of bumps, ridges etc.)
to provide good support for the building. The necessary materials
may be obtained from your local lumber yard.
To construct the base follow instructions and diagram.
