Choose a gate latch by the outside diameter of your gate tube, not the width of the gate. Most farm gates take a latch sized for either 1 1/4 to 1 1/2 inch tube or 1 5/8 to 2 inch tube. Expect to pay $25 to $58 CAD. Pick a two-way latch for any gate you open from both sides.
The short version
- Latches are sized to tube outside diameter, commonly 1 1/4 to 1 1/2 inch (32 to 38 mm) for the small size and 1 5/8 to 2 inch (41 to 51 mm) for the large.
- A standard chain-and-hook style latch starts around $25.49 CAD. A lockable two-way latch starts around $35.99 CAD.
- A two-way latch opens from either side with one hand, which matters every time you are leading stock or carrying feed.
- Zinc coating is the baseline finish for anything left outdoors through a Canadian winter.
- Electric gateways use different hardware entirely. Gate handles and anchors there run $4.19 to $14.49 CAD, not latches.
What does a farm gate latch actually have to do?
Three jobs, and most latches only do two of them well.
It has to hold the gate shut against an animal that leans on it. Cattle test gates. A 1,400 pound cow resting her shoulder into a latch applies more force than most yard hardware is built for, and a latch that flexes will eventually let the gate walk open.
It has to open when your hands are full. This is the part people underrate until they live with it. If a latch needs two hands, you will put the lead rope down, or the feed bucket, or you will prop the gate with your knee. Over a winter that is hundreds of small frustrations and a few real injuries.
It has to keep working when it is frozen, wet, or caked in mud. Most farm latches fail at the pivot, not the catch. Water gets in, freezes, and the mechanism seizes. The whole gate hardware range is built around that reality, which is why zinc coating turns up on almost every piece of it.
How do you size a gate latch correctly?
Measure the outside diameter of the gate tube, not the gate opening. This is the single most common ordering mistake.
Farm gates in Canada are overwhelmingly round tube steel, and they come in two broad sizes. Lighter yard and paddock gates use tube around 1 1/4 to 1 1/2 inch (32 to 38 mm). Heavier livestock and equipment gates use 1 5/8 to 2 inch (41 to 51 mm). Latches are sold to match one band or the other.
Take the measurement with a tape across the widest point of the tube, or wrap a string around it and divide the circumference by 3.14. If you land between the two bands, size up. A latch that is slightly loose can be shimmed. A latch that is too small will not go on at all.
Square tube gates exist and are less common. Clamp-on hardware for those, including the adjustable clamp-on hinge pairs from around $52.41 CAD, is sized the same way, by the dimension of the stock rather than the gate.
One-way or two-way: which latch suits which gate?
A one-way latch is operated from a single side. A two-way latch has a lever or handle on both faces, so the gate opens from either direction with one hand.
| Latch type | Suits | Does not suit | From (CAD) |
|---|---|---|---|
| Standard chain or hook latch | Field gates you only ever open from one side, back fences, low-traffic divisions | Any gate you work through daily, or any gate you approach from both directions | $25.49 |
| Two-way lockable latch | Yard entries, laneway gates, corral gates, anywhere stock is handled or vehicles pass | Very light gates where the hardware outweighs the gate | $35.99 |
| Electric gate handle and anchor | Gateways in an energized fence line | Any gate that needs to physically restrain an animal on its own | $4.19 |
The two-way lockable gate latch is the one most Canadian operations end up standardising on. It opens from inside or outside with one hand, takes a padlock, comes zinc coated, and is made in a large size for 1 5/8 to 2 inch tube and a small size for 1 1/4 to 1 1/2 inch. It carries a 4.7 rating across six reviews on the FenceFast catalogue.
What hardware does an electric gateway need instead?
If the gateway sits in an energized line, you are not fitting a latch at all. You are fitting a handle, an anchor and an insulated connection, and the hardware for that sits in the electric gates collection rather than with the mechanical latches.
Insulated gate handles run from $4.19 CAD for a corral handle up to $14.49 CAD for a heavy duty insulated Gallagher handle. T-post gate anchors are $8.99 CAD for a pack of two. Spring and bungy gates, which stretch across a roadway and retract out of the mud, run $47.49 to $54.19 CAD.
Two rules matter more than the hardware choice. Run the power across the gateway underground in protective pipe, buried at least 12 inches (300 mm) deep, rather than relying on the gate to carry the current. And wire it so the gate is de-energized when it is unhooked, so nobody is holding a live handle. The Province of British Columbia publishes free factsheets on gate, cattleguard and passageway construction in its Agricultural Fencing Handbook, which is worth reading before you build a gateway from scratch. For how the gate fits into the wider system, our guide on types of farm gate systems covers the layout side.
Does a farm gate latch need to lock?
On a back paddock, no. On anything touching a road, a laneway or a yard, yes, and the reason is not usually theft.
It is liability and it is accidental opening. A padlockable latch stops a gate being opened by a passer-by, by a child, or by the gate itself working loose over a season of wind. If stock get onto a road through a gate that anyone could open, the question of who left it unlatched becomes expensive. A lockable latch costs around ten dollars more than one that is not.
Lockable does not have to mean locked. Most operations run the latch unlocked day to day and pad it only on the gates that face public access. Our gate security guide goes further into which gates are worth securing.
What fails first on a gate latch in a Canadian winter?
Frost heave, then corrosion, then the pivot.
Frost heave is the one nobody designs for. Ground freezes, posts lift, and a latch that lined up perfectly in September no longer meets its catch in January. This is why a slotted or adjustable catch plate is worth more than a better latch body. If the gate can be rehung without redrilling, seasonal movement is a five minute fix rather than a job.
Corrosion is the slow one. Zinc coating handles wet, snow and the road salt that comes off a gravel driveway. Bare steel hardware on a yard gate will show rust inside one season and bind inside two.
The pivot is where it actually stops working. Water sits in the mechanism, freezes overnight and the latch will not move. A latch with a simple, open mechanism beats a clever one every time, because there is less for water to sit in and you can free it with a boot instead of a heat gun.
Which gate latch should you choose?
For most Canadian farm and livestock gates, fit a two-way lockable latch sized to your tube, and do not overthink the rest.
Measure the tube first. If it is 1 5/8 to 2 inch, take the large. If it is 1 1/4 to 1 1/2 inch, take the small. Choose the two-way version on any gate you pass through more than occasionally, because the one-handed operation pays for itself the first week you are leading an animal through it. Accept the roughly ten dollar premium for the lockable version on anything near a road.
Keep a standard chain latch for back gates and divisions you touch twice a year. There is no reason to spend $35.99 CAD on a gate you open in spring and close in fall.
If the gateway is part of an energized line, skip latches entirely and fit a handle and anchor from the electric gate hardware instead. And whichever you fit, buy the hinges at the same time. A latch is only as square as the gate hanging off it, and clamp-on adjustable hinges are what let you correct the gate when the ground moves.
Common questions
What size gate latch do I need?
Measure the outside diameter of the gate tube. Most farm gates are either 1 1/4 to 1 1/2 inch (32 to 38 mm) or 1 5/8 to 2 inch (41 to 51 mm), and latches are sold to fit one band or the other. If you fall between sizes, go larger and shim it.
How much does a farm gate latch cost in Canada?
A standard gate latch starts around $25.49 CAD. A two-way lockable latch starts around $35.99 CAD. Electric gateway hardware is cheaper per piece, with insulated handles from $4.19 CAD and T-post anchors at $8.99 CAD for a pack of two.
Can I fit a gate latch to a wooden gate?
Most round tube latches are made for steel gates. For wooden gates, use hardware designed to screw or bolt through timber, or fit a clamp-on system to a steel frame. Screw-in anchors for wood posts are available from $7.75 CAD for a two pack.
Will a gate latch work in cold weather?
Zinc coated latches handle Canadian winters well, but any latch can seize if water collects in the pivot and freezes. Choose a simple open mechanism over a complex one, and expect to realign the catch after frost heave lifts the posts.
Do I need a latch on an electric fence gate?
No. An energized gateway uses an insulated gate handle and an anchor rather than a mechanical latch. Run the power under the gateway in buried pipe at least 12 inches deep, and wire it so the gate is dead when it is unhooked.
