Pro Tip: Installing this 1ft trellis panel as a fence topper can be done in two simple ways depending on your current post setup:

Method 1 (Slotted Concrete/Timber Posts): If your fence lines feature tall, slotted posts with extra overhead clearance, simply slide this 6ft wide trellis straight down the tracks so it rests directly on top of your primary fence panel.

Method 2 (Flush Timber Posts): If your wooden posts cut off flush with your current panels, you can extend them using Timber Post Extensions or cleats. Secure two structural wooden battens vertically to the back of your existing post joints, allowing them to project 1ft over the top line. Slide your trellis between these brackets and secure it firmly with high-torque exterior wood screws for a seamless finish.

Pro Tip: Due to the large surface area of a 6ft x 6ft panel, a mature climbing plant like a climbing hydrangea or wisteria can add substantial weight and wind resistance over time.

The Professional Method: Always anchor this panel using heavy-duty structural supports. If you are fixing to timber posts, ensure you use minimum 100mm x 100mm (4″ x 4″) posts sunk at least 600mm into the ground with 1.5 to 2 bags of rapid-setting Postcrete. Secure the trellis to the inside face of the posts using stainless steel L-brackets or heavy-duty framing screws driven through the thick outer perimeter frame. Leave a clear 50mm gap between the bottom of the trellis frame and the soil layer—using a timber gravel board underneath will completely stop wet-earth moisture from wicking up into the lower framing.

Pro Tip: Adding a substantial 2ft trellis topper to the top of an existing fence requires a strong structural anchor to withstand heavy wind gusts.

Method 1 (Concrete H-Posts): If you have existing concrete slotted posts that already extend 2ft past your fence panels, simply slide the trellis panel straight down the tracks from the top until it seats tightly on the upper framing rail of your main panel.

Method 2 (Timber Posts): If your wooden posts finish flush with your current panels, use Timber Post Extensions or 2-inch structural framing battens. Screw these support battens vertically onto the inside face of your existing post joints, allowing them to bridge across the seam and project 2ft upwards. Position your trellis between the extensions and fasten securely with heavy-duty, exterior-grade wood screws driven through the thick outer perimeter frame of the trellis.
