We recommend using a 4 in. x 4 in. post with this fence panel. If your local Home Depot does not carry a 4 in. x 4 in. post in this color or style, please contact your local PRO associate to see if it can be special ordered. For information on how to attach the fence panel to the posts, please see page 4 of the installation instructions.
Mario, The distance between the posts would be 8 ft as that is the length of the fence panel.
Please contact your local PRO associate to discuss special order options.
