• 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.

LEVEL AND SQUARE FLOOR FRAME
Before installing the  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.
BEGIN

1
Use level and check the frame is level before installing  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 129-1/4" (328,3 cm).
When the frame is level and square secure one side of frame to the 4x4 runners using one fastener at ends of
each runner.
At the opposite end of the frame, secure the frame to 4x4 runners with one fastener at the end of each runner
making sure the frame remains square .
Once the  oor frame is level and square, fasten the frame at each point where the frame
contacts the 4x4 runners.
See page 9 for the preferred  oor leveling method.
Second, secure at ends
