For driveways, entrances and other wide openings where vehicles or large equipment need to pass through, double gates are a popular and practical solution.
Having two gates instead of one makes constructing a gate for a wide opening much simpler since the weight of the gates can be more evenly distributed on the hinges, while offering increased flexibility and the option to have one or both gates open at any given time.
However, double gates still present more construction and hardware challenges than single gates because they aren’t latched to a fixed structure like a fence post or wall – so it’s vital to choose the right hardware and fastenings to maximize strength, stability and security. Let’s take a look at some of the things to consider when construction a set of double gates, and the best hardware for the job.
What are the challenges of double gates?
Unlike single gates, double gates are wider and heavier, often lacking a central post for stability. This can lead to several issues:
- Weight Distribution
The increased width and weight put extra strain on hinges, potentially leading to sagging or misalignment over time. - Security
Without a central post, keeping both gates securely closed requires specific locking and latching mechanisms. - Stability
Wind or uneven ground can cause one or both gates to move unintentionally if not properly secured. This puts additional strain on hardware and can even cause the gates to swing open on their own.
Choosing hardware for double gates
As with any gate construction project, there are some key hardware components you’ll need to hang, operate and latch double gates effectively, ensuring reliable performance over time. At Abbey, we provide everything you need to complete your project, except the wood – here’s a breakdown of the must-have hardware components and how they address the unique needs of double gates:
Double gate hinges
Heavy-duty hinges are non-negotiable for double gates, because the hinges will have to bear all the weight of the gates even when they’re closed. Here are some points to consider:
Load-Bearing Capacity
Both the design and the material of the hinges you choose will influence their load-bearing capacity. Quality gate hinges are usually made from steel or iron with a hot-dipped galvanized coating, or from stainless steel, but you should also pay attention to the thickness of the material, as well as the material itself – cheaper hinges are often made from thinner metal that can warp or bend over time.
Hinges with longer or larger ‘leaves’ – that is, the metal plates that attach to the gate itself – offer better weight distribution and load bearing capacity.
You should also consider the differences between pre-assembled and drop-on hinges. Pre-assembled hinges feature two plates connected by a central knuckle, with the pin already enclosed, making them a single, ready-to-install unit. These hinges are easy to mount and provide consistent alignment, making them ideal for smaller gates or residential applications. However, removing the gate requires unscrewing the hinges, and they offer limited adjustability once installed.
Drop-on pin hinges have separate components: a pin drilled into the post and a sleeve or barrel on the gate that fits over it. This design allows for easy gate removal and adjustments, making it perfect for large or heavy gates in high-traffic or industrial settings. While they offer flexibility and durability, installation requires precise alignment, and the gate can be lifted off unless additional security features are added.
Adjustability
Look for hinges with vertical and horizontal adjustability – this means you can adjust the gate alignment without having to remove or re-hang the gates, which makes it easier to mitigate for natural expansion, contraction or movement of the gates, especially when they’re first installed.
Corrosion Resistance
As with all gates, you want to choose hinges that offer good corrosion resistance – especially in coastal climates where salt in the air can be tough on metal hardware. Stainless steel offers the best protection, but hot-dipped galvanized (which we also have available with black powder coating) is a good and affordable option.
Gate latches and locks for double gates
In order to securely latch double gates, you need hardware that will form a reliable latch between two moving parts. Conventional barrel bolts can be used to latch one gate to the other, but over time it’s very common for the bolt and the striker plate to become misaligned, resulting in gates that won’t close.
A more popular choice for double gates is a lever-style latch that lifts up and drops down into a keeper, either with a thumb latch or a ring that can be twisted. These are supplied with padlock eyes so the gate can be securely locked.
If a higher degree of security is needed, a keyed or digital deadbolt can be surface mounted onto the gates where they meet in the middle. For these mechanisms to be effective, it’s vital that the gates are perfectly aligned – the use of heavy-duty hinges and gate frames is recommended to eliminate any twisting or sagging of the gate that could render the locking mechanism useless.

Drop bolts for double gates
Another must-have item of hardware for double gates is drop bolts (also known as cane bolts) or foot bolts.
These bolts are installed vertically on the leading edge of the gate and latch down into a corresponding hole in the ground. Their purpose is to stabilise the gates so that one can be kept closed while the other is opened. They are especially important on uneven ground, where gravity can cause the gates to swing open, and also in exposed locations – they prevent wind from causing the gates to rattle, which can lead to the central latch or bolt from working loose.
Conventional drop rods or cane bolts are operated manually, while foot bolts are usually shorter with a pedal that enables them to be opened or closed with your foot.
Gate wheels for double gates
Given their additional width and weight, double gate arrangements are often fitted with gate wheels to help with load bearing and prevent sagging of the gates over time.
Available in hot-dipped galvanized, zinc and powder coated options, Abbey’s range of gate wheels is designed for reliable, long-term performance and simply attaches to the bottom inside corner of the gate, then rolls along the ground when the gate is opened and closed, reducing the burden on the hinges. Our gate wheels come with a spring-loaded ‘suspension’ and swivel wheels for a smooth rolling action on all surfaces including asphalt, paving and gravel.
Additional hardware for double gates
Once your gate is securely hung and fitted with an appropriate latch and/or lock, you can turn your attention to additional hardware that improves the practicality and aesthetic of the gate. Here are some other components you might wish to add:
Handles or pulls
If you’ve opted for a simple gate latch without a handle, you may wish to install a separate gate pull or handle to make it easier to open the gate. These can take the form of a ring, bar or thumb handle. Choose durable materials with a corrosion-resistant finish to keep your double gates looking smart for many years to come.
Decorative hinge fronts
If you want to add a decorative flourish, hinge fronts can be a great option! The functional hinge is fixed to the back of the gate so it can’t be seen from the outside, while a decorative faux hinge plate goes on the front of the gate – we offer these in a range of beautiful antique styles.
Grills, bells and signage
For the perfect finishing touch on residential double gates, we offer a range of gate accessories including numbers, knockers, grills, studs, clavos and even bells. Add simple instructions with a ‘please close the gate’ or ‘beware of the dog’ sign – explore the full range here.
Trust Abbey for quality gate hardware
Investing in high-quality hardware is essential for the longevity and functionality of double gates. As fencing professionals know, poorly chosen hardware can lead to callbacks, added costs, and dissatisfied clients. By selecting durable, weather-resistant components, you can ensure your installations stand the test of time.
