Assemble the Main Frame
1.1 Using 3 1/2" x 3 1/2" pressure-treated lumber, install the beams using the drawing below as a
reference. You will need two boards cut to 5'-8 1/2" that will be studs and two boards cut to 5'-5" that will
be horizontal girts.
1.2 Secure the beams to the bottom rails with 5", 2" wood screws and 3" x 3" corner brackets.
