The Cannon is a modern flat-top picket built to follow the ground: it racks with the grade instead of stepping across it.
Powder-coated smooth- Follows the lay of the land
Catalyst states it works on sloping grades and flat surfaces, which is the reason to specify it on a yard that falls.
- Secure with a view
A two-rail flush-bottom build: enough fence to hold the line, open enough to see through.
- An optional puppy picket
Catalyst names children and pets around home and pool perimeters.
- Two colors
Black and Bronze are both offered, which is more than most of the line.
- No visible hardware
The NoVis™ hidden fastener system locks the panels together on level and sloping ground without visible screws.
- A finish that is baked on
Every aluminum component is powder coated before assembly, so there are no bare spots, and SolarGuard® keeps the color from fading.
- Made by Catalyst, installed by us
Catalyst Fence Solutions manufactures the Cannon, and the image above is its product visualization, not a photograph of a Chonko Construction job. We are the installing builder.
The Cannon is offered in one tier and two colors.

Height 4 feet, flush bottom, in a two rail build.
- checkPanel widths. 6 feet. Walk gates and drive gates are built to match the panel, and we set post depth and spacing to the height you choose.
Pick the Cannon when the yard is not flat.
It racks with the grade, so there are no stepped gaps under the panels.
Catalyst names the puppy picket for children and pets around a pool. We check the code for your address.
Two rails and a flat top is the least fence that still does the job.
- air
A taller run. The Cannon is a 4 foot fence. Lexington covers the same idea at up to 6 feet.

Three finials. Triad, Quad and Fleur-de-lis finials sit on the post in place of a flat cap.

Rail adornments. Butterfly scrolls and circles mount into the rails themselves, which is what separates a decorative aluminum run from a plain one.

The solar cap lights the line. Catalyst's Solar Post Cap puts off-the-grid landscape lighting on the posts, with no wiring to run.

Pick it with the style. The cap is the part of the fence you see at eye level from the house. We price the caps with the panels, so it is one number rather than a change order later.
For the Cannon, the number moves with linear footage first, then the height you choose (4 ft), the gates, and the ground the posts go into. The full breakdown of what moves an aluminum fence price is on the aluminum fence page; we set the exact figure in writing after we walk the property.
Want real numbers? Our aluminum fence cost guide breaks down what an aluminum fence runs per linear foot in the Midlands, and the all-materials fence cost guide compares it to the other fence types. Whatever your number, it is set in the contract before any post hole is dug.
Warranty and Who Installs It
Two warranties cover a Cannon we install.
Catalyst backs its fence with a transferable limited lifetime warranty; the warranty document carries the terms.

Aluminum in the Midlands
Aluminum is the low-fuss fence for the Midlands.
- Humidity. Aluminum does not rust, and the powder coat is baked on.
- Heat. Summer heat does nothing to it.
- Wind. Open pickets let storm wind through, so the panels carry less load than a solid fence, and the posts are set in concrete to hold the line.

Frequently Asked Questions
What does racking mean?add
The panel flexes so the pickets stay vertical while the rails follow the slope. The alternative is stepping the panels level, which leaves triangular gaps underneath.
Does the Cannon meet pool code?add
Catalyst names the puppy picket for pool perimeters. Pool barrier code turns on height, gaps and gate hardware, so we check the code for your address and specify a height and gate that meet it before anything is ordered.
How tall is the Cannon?add
Four feet. It is offered at one height, in a flush bottom build.
What is a 2 rail aluminum fence?add
The Cannon is a modern flat-top picket built to follow the ground: it racks with the grade instead of stepping across it. The Cannon is Catalyst Fence Solutions' version of it, and Chonko Construction installs it across Columbia and the Midlands under one written contract.
What heights does the Cannon come in?add
4 ft. We match the height to the job: privacy and pool code want the taller end, a front-yard boundary usually wants the shorter.
Can the Cannon be installed on a slope?add
Yes. On a grade we rack or step the panels so the fence follows the slope and stays level, and we show you which approach fits before any post is set.
Which colors does the Cannon come in?add
2 colors: Black, Bronze. Ask which are quick-ship, because it changes the start date.
