ASSEMBLING AND POSITIONING THE BASE RAILS:
Layout the base rails on your slab or footing or prepared ground. The base rails should be 10’, 12’, 14’, 16’, 18’, 20’, 24’,
or 30’ apart (outside to outside) depending on the carport that you purchased. The length from the front to the back of the
base rail assembly will be 1/2” longer than the frame length. (Example: If you have a 20’ x 20’ frame, the length of the
base rail assembly will be 20’-1/2”. The dimension from the front of the front vertical pin to the back of the back vertical
pin will be 20’.) Note that the base rail layout for 5’ and 4 1/2’ On Center frame sections is the same. The layout for 4’ On
Center frame sections is different. On 4’ On Center frames, the length of the basic base rail assembly will be 20’- 2 1/2”
from the end of the front base rail to the end of the back base rail.
Join all the base rail components as shown. Check the overall length of the assembly, keep the swage joints even in
length and fasten the swage joints with (2) #12 hex head, self drilling screws per joint on top of the base rail.
Place the Left and Right base rail assemblies 10’, 12’, 14’, 16’, 18’, 20’, 24’, or 30’ apart (outside to outside) and take a
measurement across the diagonals of the frame to check it for square. Adjust the frame until the measurements are
equal.
