SQUARING THE FRAME
Measure diagonally corner-to-corner from the same point as shown below.
The frame is square when the two diagonal measurements are equal. The
recycled plastic lumber is flexible. Verify that the side rails are straight before
anchoring the base and assembling the greenhouse.
Anchor the base to the site after it is square and before you assemble the
greenhouse components.
