STEP 4a:
Take 2 board to timber connectors and fasten them on either side of
the bottom animal barrier gate pole with the screws provided and a power drill.
This will allow the animal barrier gate and board gate to swing as a complete
door.
STEP 4b:
For a 3-level design, take your metal gate brace and fasten it over 2 of
the left gate boards with the screws provided and a power drill. Install the gate
braces on the inside portion of the garden and make sure that the screw holes
are not over the edge where the 2 boards meet (see picture).
Repeat this step for the right gate. For a 4-level design, install
an additional gate brace on each door.
