FLOOR LEVELING OPTIONS
There are multiple ways to level your oor frame. Our recommended leveling method is shown below.
Leveling materials are not included in this kit.
PREFERRED METHOD - 4x4 TREATED RUNNERS
• 3" Screw angled into 4x4.
• (2) at each point frame
and 4x4 touch.
4x4 Runners
(not included)
• Level under 4x4 runners only.
• Locate leveling material 12" from ends of runners and no more than 48" apart.
• Asphalt shingles should be used between 4x4 runners and blocks or treated lumber.
Never use shingles in direct contact with ground.
• For best results and aiding in water drainage use gravel under each concrete block.
LEVELING METHODS
• If you are building your shed on a concrete foundation see page 7.
CONCRETE
Fasteners for Frame to 4"x 4".
(3" Screws shown as one option.) Minimum (40) 3" screws / exterior grade.
Use only wood treated for ground contact and fasteners approved for use with treated wood.
Always support frame seams.

• A treated 2 x 4 (5,1 x 10,2 cm) sill plate is required when installing your shed on concrete. Hint: Use treated lumber in your kit or
purchase full length treated lumber.
• Use a high quality exterior grade caulk beneath all sill plates.
• Fasten 2 x 4 (5,1 x 10,2 cm) sill plates to slab using approved concrete anchors (fasteners not included).
• Check local code for concrete foundation requirements.

LEVEL AND SQUARE FLOOR FRAME
Before attaching oor decking, it is important to level and square the oor frame.
A level and square oor frame is required to correctly construct your shed.
2
3
4
Use level and check the frame is level before applying oor panels.
Check for frame squareness by measuring diagonally across corners. If the measurements are the same, the
frame is square. The diagonal measurement will be approximately 173-1/16" (439,6 cm).
When the frame is level and square, secure one side of frame to the 4x4 runners with one fastener at ends of
each runner.
Move to the opposite end of the frame.
Secure the frame to 4x4 runners with one fastener at ends of each runner, making sure the frame remains square
(Fig. A).
Once the oor frame is level and square fasten the frame to at each point the frame
contacts the 4x4 runners .
See page 7 for the preferred oor leveling method.
