How to Fit a Garden Gate Latch or Bolt
Choose and fit a thumb latch, ring latch or bolt on a timber garden gate, with positioning, alignment, child-safety height and weatherproofing tips.
A gate that swings open in the wind or will not stay shut is more than an annoyance. It lets pets and children wander and invites opportunist visitors. A good latch fixes this for little money. Fitting one is straightforward, but the details, such as alignment, height and weatherproofing, decide how well it lasts.
Choose the latch
- Thumb latch (Suffolk latch). A traditional design with a thumb press and a latch bar. Attractive and easy to use.
- Ring latch. A ring handle that lifts the latch. Robust, popular on timber gates.
- Spring-loaded or magnetic latch. Self-closing, often used where pool or child safety rules apply.
- Bolt. Sliding bolts add security, either on the inside or at the bottom.
- Padlock hasp and staple. For higher security or sheds.
Pick galvanised, stainless or powder-coated steel for outdoors. Cheap uncoated fittings rust and stain timber.
Position it correctly
The latch should be set at a height that suits users, typically around 1 to 1.2 metres from the ground. If the gate is part of a play area or near a pool, safety guidance may require a self-closing, self-latching gate with a latch positioned out of the reach of small children. Check the rules that apply to your setting.
The latch needs solid timber to bite into. Fix it to the gate stile, not to thin boards, and the keep (the catch) to the post. If the post is out of true or the gate sags, fix the gate first; see how to fix a sagging garden gate.
Tools and materials
- Latch set, with screws appropriate for outdoors
- Drill and bits, plus a countersink
- Screwdriver
- Pencil, tape measure and spirit level
- Chisel, if you need to recess the keep
- Wood preservative or paint for any exposed timber
Step by step
- Close the gate and hold it where it should sit in the frame, with an even gap. Have someone hold it or wedge it.
- Mark the latch position on the gate and the keep position on the post. For a thumb latch, mark where the latch bar will fall on the keep.
- Fit the latch plate to the gate. Drill pilot holes to avoid splitting, then screw in place. If the latch has a backplate, check it is level.
- Fit the keep to the post. With the gate closed, line up the latch bar with the keep and mark the screw holes. Drill pilot holes and fix.
- Test. Open and close the gate several times. The latch should drop smoothly into the keep with no rattle.
- Adjust. If it rattles, slightly shift the keep. If it binds, enlarge the opening in the keep or trim the post with a chisel.
- Treat. Touch up any cut or drilled timber with preservative.
Fitting a bolt
Fix the bolt on the inside of the gate where a person cannot reach through the slats, ideally with a keep drilled into the post or the ground. Use long screws into solid timber. A padlock hasp should be fitted so the screws are covered when the gate is closed.
Common mistakes
- Fixing into thin or rotten timber
- Using short screws that pull out
- Setting the keep too high or low so the latch catches only partly
- Forgetting to check the gate swings freely
- Placing the latch where it can be reached from outside through slats, if privacy or security matters
Maintenance
- Oil moving parts annually.
- Tighten screws after the first few weeks.
- Replace worn latches before they fail.
- Check the gate and post remain square.
Costs and help
A latch is a small job, often included in a wider garden list with fence repairs. The labour is usually quick, so the minimum charge may apply; see handyman minimum call-out charges.

Choosing between latch types for your situation
| Situation | A sensible choice |
|---|---|
| Side gate, general use | Ring or thumb latch, galvanised |
| Gate near a play area | Self-closing, self-latching gate fittings |
| Shed or gate you want locked | Hasp and staple with a closed-shackle padlock |
| Metal gate | Latch designed for metal, with through-bolts |
| Wide double gate | Drop bolt at the bottom of one leaf, latch on the other |
Setting the gap
A gate needs a gap of a few millimetres on the latch side to allow for timber swelling. If the gate is tight in wet weather, fit the latch with a little extra room, or plane the edge. A latch that is perfect in summer and jams in winter is a symptom of a gate that is too tight.
A note on security
A latch on its own is not a lock, and a determined person can reach over many fences. If you want the gate to be secure, consider a lock or bolt that cannot be reached through the slats and fit a gate that is high enough for your needs. Check the local height rules before raising anything beside a road.
Renting and shared gates
If the gate is shared with a neighbour or belongs to a landlord, ask before replacing fittings. A like-for-like latch swap is rarely a problem, but agree in writing. For wider guidance, see handyman work in rented homes.
Frequently asked questions
What height should a gate latch be?
Typically around 1 to 1.2 metres for general use. For child-safety applications, follow the guidance for your situation.
Can I fit a latch to a metal gate?
Yes, but you will need suitable fixings and may need to drill or weld. For heavy metal gates, a metalworker may be best.
Why does my latch keep missing the keep?
The gate is probably sagging or the post has moved. Fix the underlying movement first.
