12'x20'x8' is the BASE frame dimension. Your model may have more middle ribs than shown in the illustration on

assembly will remain the same. The cover will be the correct size for the length of the building you purchased.
1. PLOTTING THE FRAME:
Before building your shelter, you should choose a flat area on
your property and plot your shelter.
A. Stake out the area for the shelter in the desired spot. The width of
the area should be at least equal to the width of the shelter and the
length should be equal to the length of the shelter Fig. 1.
B. Measure diagonally from corner to corner (A & B). These
measurements should be the same. If they are not equal the stakes
need to be adjusted until the width, length and inside measurements
are correct.

fasten all of the joints with the hardware indicated.
3. ASSEMBLE MIDDLE RIBS
