What Is a Cantilever Gate?

Around the world, there are various sliding gate designs. These can vary based on local fence construction guidelines and site conditions.  In North America, where cold weather frequently makes it difficult to drill into gate posts and where snow and ice can collect along standard gate tracks, sliding gates often feature a cantilever design. Let’s examine what cantilever gates are, why they use this design, and what you need to know if you’re considering this style of sliding gate.

What Does a Cantilever Gate Look Like?

A cantilever gate usually appears similar to other sliding gates, but it includes a long section of gate frame—known as a cantilever tail—that extends roughly half the width of the gate opening on the side toward which the gate slides open.

Why Do Cantilever Gates Use Rollers?

Rollers are central to the cantilever gate’s ability to function in adverse conditions. Since a cantilever gate slides on rollers bolted to the support posts, there are no wheels making contact with the ground. This helps the gate operate reliably, even if snow builds up below.

Cantilever rollers allow the gate to operate about 6 to 12 inches above ground level, which enables the gate to open and close even if there is a fair amount of snow accumulation. The main drawback of this design is the gap below the gate, which can cause security concerns in areas where the ground slopes significantly, leaving a larger space at one end of the gate.

What Are the Components of a Cantilever Gate System?

The components of a cantilever gate system depend on the fence type. Cantilever gates can be made for chain link fences, ornamental fences, or even wood fences. Hardware may vary slightly, but typically you’ll have one latch post on the closing side (two if you choose automation and need a V-catch), a pair of roller posts on the opening side, the cantilever rollers themselves, and a gate that includes a fully clad panel plus a lighter cantilever trailer section.

Are Cantilever Gates Usually Installed Inside or Outside the Fence Line?

Because cantilever gates commonly serve commercial or industrial sites where security is a priority, they are often installed inside the fence line or next to a solid barrier such as a wall. This arrangement helps protect gate hardware from outside tampering, enhancing overall security.

Can You Install Double Cantilever Gates?

Yes. Cantilever gates can be installed in a double configuration. In this setup, each gate leaf has its own pair of roller posts. The two gate leaves then meet in the middle, effectively latching to each other and eliminating the need for a single latch post.

Can Cantilever Gates Be Automated?

Many property owners who need easy access and a higher level of security choose to automate cantilever gates. There are many automation and access control systems on the market suitable for cantilever gates, including keypads, card readers, and remote-control openers.

What Do You Need to Consider When Installing a Cantilever Gate?

There are several considerations when planning a cantilever gate:

• Space Requirements: Cantilever gates need about one-and-a-half times the width of the actual gate opening on the side used for the slide path. If your site does not have adequate space on one side, consider reversing the direction or installing a double cantilever gate for a more balanced approach.

• Ground Conditions: Cantilever gates generally require level ground for proper installation. While they can handle moderate terrain variations, sites with pronounced slopes may need alternative solutions.

• Security Needs: In many places, including Phoenix and surrounding Arizona communities, cantilever gates are commonly installed for commercial projects requiring secure perimeter fencing. If you’re in a high-traffic area, you can integrate automated systems to help with controlled entry.

Where Are Cantilever Gates Usually Installed?

Cantilever gates are frequently found on commercial and industrial sites that prioritize security, such as warehouses, manufacturing facilities, and multi-tenant complexes. They are also popular with property owners who prefer to avoid ground tracks or require uninterrupted ground access for vehicles or equipment.

How Much Does a Cantilever Gate Cost?

Cantilever gates are heavier and more complex than basic sliding gates, requiring robust hardware and sturdy posts. The final price varies based on gate size, materials, and any additional automation features. Expect to invest several thousand dollars, with costs rising further if you include gate operators, advanced access control, or custom design elements.
