When to Brace:
-Anytime you use a straight join to create a longer run, you need to brace the panels. 1 per panel.
-Anytime you use the longer 78" panel, you need to brace - 2 per panel recommended.
Option 1 - Anchor post and bracket kit (comes with both the post and the bracket to attach it.) Use anywhere on the panel that you feel needs support.
Option 2 - The Universal Bracing. These hook onto any straight joins (instead of bracing in the middle of the panel, brace the joins.) If you are using the 78" panel though, the only choice is the anchor post and bracket kit to enable you to brace in the middle of the panel.
