Questions about fence toppers

FenceTopper is a fence extension privacy system. A tensioned outdoor mesh panel runs between extension posts on your existing fence and adds 12 to 24 inches of screening, in 1 inch steps, so you can make your fence taller without replacing it.

Add extension posts to your existing fence posts, then mount a fence extension between them. On chain link and other round steel posts, extenders slide into or over 2 3/8 in or 1 5/8 in posts. On wood fences, extenders fasten to the face or side of 4x4 posts. A mesh extension panel then adds 12 to 24 inches of privacy above the fence.

You can choose any height from 12 to 24 inches, in 1 inch steps. Most customers choose 18 inches, which turns a 6 ft fence into 7 ft 6 in. Go lower for a low sightline such as a neighbor’s patio, and higher when you need to screen a deck or a second-floor window. The visualizer shows any height on a photo of your fence.

Measure each straight, level run of fence from end post to end post in feet and inches. Where the fence turns a corner or steps up or down, start a new run, and leave out gates. Measure your fence height too. The measuring guide walks through it and the price builder turns your runs into a price. Fences that follow a continuous slope are not currently supported.

Yes. You or your contractor install the fence extenders (the posts that hold the topper above your fence), then slide the panel over the inner posts, wrap the end straps around the outer posts, pull them snug and set the height with a screw at each center post. The installation guide shows each step.

A tape measure, a drill or driver, a level and a pencil. Fence extenders and their mounting hardware aren’t included; see the options on our Fence extenders page.

The extension mounts on posts, not on the fence face, so it works on most fence types. Chain link and other round steel posts take extenders sized to the post. Wood fences use extenders fastened to 4x4 posts. It’s shown on cedar, horizontal slat, painted wood and composite fences. Send us a photo through support if you’re unsure about your fence.

At a 90-degree corner, two separate straight panels meet at one shared corner post. Each panel ends with its own straps and removable cover, so the fabric never has to bend around the corner.

The panel is tensioned from both ends through pull-through strap adjusters, and fiberglass battens keep the edges straight. All posts hold the panel at the same height, so there is no dip at the center posts. You can re-tension the straps at any time.

The fabric is a woven outdoor mesh, so air passes through it instead of loading the fence like a solid board. It has a water-repellent acrylic-coated finish. Wind and UV ratings will be published once testing is complete.

Carbon, Black, Evergreen and Brown. Carbon is the most popular and suits most fences. Order a swatch kit if you want to compare colors against your fence first.

$14 per square foot of topper, plus $40 for each middle post and $120 for each panel. Enter your runs in Shop for an estimate.

Many cities limit backyard fence height to 6 to 8 ft, and HOAs may have their own rules. Check your local code and HOA before you order. Because the extension comes in 1 inch steps from 12 to 24 inches, it’s easy to pick the tallest one that stays under your limit.

Yes. Loosen the straps, lift the panel off the posts and store it dry. The posts can stay in place.

No. You or your contractor provide and install the fence post extenders that hold the panel above your fence. Our Fence extenders page shows the options by fence type, and we build the panel to fit your approved layout.

It depends on your fence. Round steel posts take an insert-style extender sized to the post, such as the OZCO internal extender for 2 3/8 in posts or a swaged extension for 1 5/8 in posts. Wood fences can use a face-mounted leg or a pipe bolted to the side of a sound 4x4 post. Our Fence extenders page shows each option and what it fits.

Each extender should rise about 1 in above the topper. On a level run, cut an OZCO tube 1 in longer than the topper height, so a 24 in topper uses a 25 in tube. If your post tops aren’t level, set the two end extenders, stretch a mason’s line between them and cut each middle extender to meet the line.

Yes. Describe it when you send us your project, or email us a photo or drawing with its profile and size. We’ll review whether the topper can be adapted to it. That review isn’t an engineering approval.

It’s up to you and depends on the option. Side-mounted pipe on wood posts is best done by a contractor. Either way, make sure your posts, footings and fasteners can carry the taller fence, and check your local height rules.
