Gate Installation Guide
How to Choose Gate Hinges and Fittings
The right hinges and gate fittings depend on the gate’s size, weight, construction and how it will be used. This guide explains the main hinge, latch and bolt options and what to check before ordering.

Before You Choose
The correct gate fittings depend on more than the gate width alone.
Before ordering, check:
- Gate width
- Gate height
- Gate construction
- Approximate gate weight
- Post material
- Post size
- Opening direction
- Ground conditions
- Wind exposure
- Required security
- How often the gate will be used
A small pedestrian gate may only need simple tee hinges and a standard latch. A wide or heavy gate may require adjustable hook-and-band hinges, substantial posts, bolts and additional support.
Make sure all fittings are suitable for outdoor use and compatible with the gate and post materials.
Understanding Gate Weight and Width
As a gate becomes wider or heavier, it places more load on the hinges and hanging post.
This is caused by leverage. The further the gate extends away from the post, the greater the force acting on the hinges.
Factors that increase the load include:
- Greater gate width
- Greater gate height
- Solid timber construction
- Tongue-and-groove boards
- Closeboard construction
- Wet timber
- Decorative framing
- Heavy ironmongery
- Wind exposure
A lightweight open gate may place less strain on the post than a narrower solid gate.
Before choosing fittings, consider:
- Whether the post is large enough
- Whether the post foundation is secure
- How far the hinge band spreads across the gate
- Whether adjustment will be needed
- Whether the gate may be automated later
Do not use light-duty fittings simply because the gate fits within the opening.
Tee Hinges
Tee hinges are commonly used on lighter pedestrian and side gates.
They consist of:
- A long strap fixed across the gate
- A shorter vertical section fixed to the post
- A central hinge pin
They are suitable for:
- Small garden gates
- Lightweight ledged-and-braced gates
- Picket gates
- Narrow side gates
- Light-duty access gates
Advantages
- Simple to fit
- Widely available
- Suitable for many standard garden gates
- Usually cost-effective
- Available in different lengths and finishes
Check before buying
- Hinge length
- Gate weight
- Gate rail position
- Screw-hole size
- Post material
- Finish and corrosion protection
The hinge strap should fix into a structural rail or frame, not only into thin face boards.
Longer tee hinges normally spread the load better than very short hinges.
Hook-and-Band Hinges
Hook-and-band hinges are suitable for heavier timber gates.
They normally consist of:
- A long hinge band fixed to the gate
- A hook or pin fixed to the post
- A circular eye at the end of the band
They are commonly used for:
- Framed garden gates
- Closeboard gates
- Tongue-and-groove gates
- Five-bar gates
- Wide side gates
- Heavy pedestrian gates
Advantages
- Strong construction
- Good load distribution
- Suitable for wide gates
- Available in straight and cranked forms
- Can often be replaced independently
Straight or cranked bands
Straight bands are commonly used where the gate sits behind or in line with the post face.
Cranked bands can offset the gate position and may allow the gate to sit more neatly within the opening.
The correct type depends on:
- Post position
- Gate thickness
- Required opening angle
- Whether the gate is fitted between or behind the posts
Check the intended installation arrangement before choosing.
Adjustable Gate Hinges
Adjustable hinges allow the gate position to be altered after installation.
They are useful for:
- Wide gates
- Heavy gates
- Five-bar gates
- Driveway gates
- Openings that are not perfectly square
- Timber gates that may move seasonally
- Installations where precise alignment is important
Adjustment may allow the gate to be:
- Raised
- Lowered
- Moved towards or away from the latch post
- Aligned more accurately with a paired gate
Adjustable systems commonly use:
- Threaded hinge pins
- Nuts and washers
- Adjustable eyes
- Heavy-duty brackets
Leave some adjustment available in both directions during installation. Avoid setting the hinge at the extreme end of its adjustment range from the start.
Hinges for Five-Bar and Driveway Gates
Five-bar and driveway gates are wider and often heavier than standard pedestrian gates.
They normally require:
- Long hook-and-band hinges
- Adjustable hinge sets
- Substantial hanging posts
- Heavy-duty bolts
- Ground stops
- Drop bolts for paired gates
- Suitable exterior fixings
Before choosing driveway gate hinges, check:
- Gate width
- Gate weight
- Timber section sizes
- Post dimensions
- Single or paired arrangement
- Opening angle
- Ground slope
- Wind exposure
- Whether automation may be fitted later
Paired gates need careful alignment so both leaves meet correctly in the centre.
For very large or heavy gates, professional installation may be advisable.
Choosing a Gate Latch
The latch should suit the gate’s purpose, security requirement and method of operation.
Common options include:
Suffolk latches
Suffolk latches are a traditional choice for timber garden gates.
They are operated by a thumb lever and are suitable for regular pedestrian access.
Ring latches
Ring latches can usually be operated from both sides of the gate.
They suit:
- Garden gates
- Side gates
- Courtyards
- Traditional timber gates
Automatic gate catches
Automatic catches engage when the gate closes.
They are useful where:
- The gate is used frequently
- Simple operation is preferred
- The gate needs to close securely behind the user
Lockable latches
Lockable latches provide additional security.
Check whether the latch is:
- Padlockable
- Key-locking
- Operable from one or both sides
- Suitable for the gate thickness
- Suitable for outdoor use
Position the latch at a practical height and ensure the receiver aligns correctly.
Choosing Bolts and Stops
Bolts and stops help secure the gate and control its movement.
Sliding bolts
Sliding bolts are commonly used to secure pedestrian and side gates.
They may be fitted at the top, middle or bottom.
Drop bolts
Drop bolts are commonly used on driveway gates and paired gates.
They secure one gate leaf into:
- A ground socket
- A concrete stop
- A prepared hole or receiver
Monkey-tail bolts
Monkey-tail bolts have a curved handle and are often used on wide timber or driveway gates.
Gate stops
A gate stop prevents the gate from swinging too far or placing excessive strain on the hinges.
Stops may be fitted to:
- The ground
- A wall
- A post
- The centre of paired gates
Choose positions that do not create a trip hazard or obstruct vehicles.
Fixings and Fasteners
The fittings are only as secure as the screws or bolts holding them.
Use exterior-grade fixings suitable for:
- The hinge thickness
- Gate timber thickness
- Post material
- Timber treatment
- Expected load
- Outdoor exposure
Possible fixings include:
- Exterior screws
- Coach screws
- Coach bolts
- Nuts and washers
- Masonry anchors
- Threaded fixings
- Manufacturer-supplied bolts
Important points
- Drill pilot holes where needed.
- Avoid splitting timber near edges.
- Use washers with bolts where appropriate.
- Do not use fixings that pass completely through the timber unless this is intended.
- Do not rely on small screws for heavy gates.
- Check compatibility with treated timber.
- Retighten fixings after the gate has been used.
Where fixing to masonry, make sure the wall or pillar is sound and the fixing type is suitable.
Security and Locking Options
The required security level depends on the gate location and use.
Options include:
- Padlockable sliding bolts
- Lockable ring latches
- Key-operated gate locks
- Digital gate locks
- Drop bolts
- Anti-lift hinge arrangements
- Concealed fixings
- Gate closers
- Additional internal bolts
For improved security:
- Use strong posts
- Choose substantial hinges
- Prevent the gate being lifted off its hinge pins
- Keep fixings inaccessible where practical
- Use a latch suitable for the gate thickness
- Make sure the gate frame is strong enough
- Avoid leaving large gaps around the gate
Security fittings should not make the gate difficult to use safely or prevent essential access.
Common Fitting Mistakes
Avoid these common problems:
- Choosing hinges only by appearance
- Using hinges that are too short
- Fitting hinges into thin boards rather than the frame
- Using a light-duty latch on a heavy gate
- Hanging a wide gate from an undersized post
- Using indoor screws outdoors
- Fitting bolts where they cannot operate freely
- Forgetting to allow for ground clearance
- Setting adjustable hinges at the end of their range
- Choosing fittings before deciding the opening direction
- Failing to check the gate thickness
- Using incompatible masonry fixings
- Overtightening screws and splitting timber
- Failing to fit a stop on a gate exposed to wind
- Forgetting centre bolts on paired gates
- Using a lock that cannot be operated from the required side
