Espagnolette Window Handles Explained: Types, Fitting and Finishes

Espagnolette window handles are the lever handles that operate an espagnolette window system - the long locking bolt that runs down the edge of the opening sash. At Trade Door Handles we stock and supply a large range of espagnolette window handles to suit timber, steel and uPVC windows, in a wide choice of finishes and styles to match your decor.

Supplied by Trade Door Handles, trusted UK supplier of architectural ironmongery since 1976, with quick nationwide delivery.

This guide explains what espagnolette window handles are, how the locking mechanism works, the handing and sizing you need to get right, and how to choose the correct espagnolette window handles whether you are fitting a new window or replacing worn hardware.

An espagnolette window handle is a lever mounted on a backplate that drives a multi-point locking system. When you turn the lever it rotates a spindle, and that spindle moves the espagnolette bolt - a continuous rod, often shortened to "espag" - up and down behind the handle. Cams or rollers along the rod engage into keeps fixed to the frame, pulling the sash tightly closed at several points at once. This is why espagnolette window handles are found on so many modern casement and tilt-and-turn windows: they give a secure, weather-tight seal along the whole edge of the sash rather than at a single point.

Trade counters and installers often shorten the name to espag handles or espag window handles, but they all describe the same family of lever handles that operate an espagnolette bolt.

An espagnolette window is any window that closes and locks using an espagnolette bolt instead of a simple catch or fastener. The bolt is concealed within, or fixed to the back of, the opening sash. As the handle turns, the whole bolt shifts and locks into multiple keeps, which is what makes the system so weatherproof and secure. The style suits UK weather well, which is why it has become the standard on double glazed windows.

Espagnolette window furniture is the collective term for the handles, keeps and locking bars that make up the system. You can see the full choice in our espagnolette window furniture collection, which sits within our wider window furniture range. In everyday use, most people are searching for the visible lever - the espagnolette window handles - but it is worth knowing the keeps and bolt are part of the same family.

The principle behind espagnolette window handles is simple once you picture it. The lever turns a spindle that passes through the window into the espagnolette bolt. Turning the handle drives the bolt along the edge of the sash, and cams (sometimes called mushroom cams or rollers) ride into the frame keeps. Because the sash is drawn in at several points, espagnolette window handles hold the window firmly against its seals with no gaps.

The locking mechanism is a length of gearing inside a face plate, driven by the handle spindle. Modern espagnolette gearing can include just the bolt, or a combination of bolt, rollers and a deadbolt or hook for higher security. Turning the handle to the closed and downward position throws all the locking points together, which is the multi-point action that gives espagnolette window handles their strength.

Espagnolette window handles come in two main types: non-locking and key-locking. A non-locking handle simply operates the bolt and holds the window shut. A key-locking (lockable) handle adds a small barrel so the lever can be locked in the closed position, which is useful for extra security, insurance requirements and child safety.

You will see the locking hardware on espagnolette window handles described in a few different ways, but it all refers to the same espagnolette system:

• Espag window lock or espag window locks - the trade shorthand, where espag is simply short for espagnolette.
• Espagnolette window lock or espagnolette window locks - the full name for the locking gear behind the handle.
• Lockable window handle or locking window handle - a general description of any key-locking lever.

If you specifically want a key-lockable option, look for an espag window lock or a handle listed as lockable. Both locking and non-locking espagnolette window handles fit the same gearing, so you can usually upgrade a plain lever to lockable espagnolette window handles without changing the whole system.

One of the biggest advantages of espagnolette window handles is their versatility. Because it is the bolt behind the handle that does the locking, the same style of espagnolette window handles can be used across timber, steel and uPVC windows.

On timber windows, espagnolette gearing is routed into the edge of the sash and the espagnolette window handles are fixed to the face. Fitted this way, espagnolette window handles give a traditional timber window the same multi-point security as a modern unit, which is popular on new hardwood and heritage-style joinery.

Steel windows, including period Crittall-style frames and their modern equivalents, also use espagnolette hardware. Slim steel sections suit narrow gearing and neat espagnolette window handles, and finishes such as matt black or pewter complement the industrial look. From The Anvil is a popular choice here for its steel-window and black hardware ranges.

uPVC is the most common type of window you will see espagnolette window handles on, and most replacement uPVC window handles are this espagnolette type. On a uPVC window the handle bolts onto a multi-point locking gearbox built into the edge of the sash, so turning the lever throws the locking bolt along the frame.

When choosing or replacing espagnolette window handles for uPVC, what matters is the spindle and the handing, not the frame itself. The square spindle comes in two forms: inline (straight), where it projects straight out from the handle, and cranked, where it is stepped back so the handle sits slightly raised or set into a recess. You then match the spindle length, the fixing centres (commonly 43mm on uPVC) and the handing — left, right or universal — to your existing espagnolette window handles. White is still the traditional colour on uPVC and aluminium windows, though black and chrome espagnolette window handles are now just as popular.

Espagnolette window handles are supplied in three handings - straight (universal), left hand and right hand. Getting the handing right is essential, because espagnolette window handles fitted the wrong way will point up when the window is locked or foul the reveal.

A straight handle, also called a universal handle, can be fitted either way and covers both left and right openings. Straight espagnolette window handles are the most flexible choice and a sensible stock item for installers. Browse our straight espagnolette handles if you want one handle that suits either side.

The one thing to watch is clearance. Because a straight handle points the same way whichever side it is fitted, on some windows the lever can end up sitting close to the frame or reveal, which can mean catching your knuckles or finding it stiff to turn. Where that happens, a cranked spindle or a dedicated left or right hand handle usually gives more room, so it is worth checking the reveal before settling on straight espagnolette window handles.

Not every manufacturer makes all three handings of espagnolette window handles, so what you can choose from depends on the range. Some ranges offer only a straight universal handle, while others — particularly those with cranked or sculpted traditional levers such as monkey tail patterns — are made specifically as a handed pair, giving you a separate left and right version rather than a universal one.

Where a range is handed, choose from our left hand espagnolette handles or right hand espagnolette handles depending on which way your window opens. Picking the correct hand means the espagnolette window handles sit properly and look right in both the open and closed positions. As a rule, a straight handle keeps things simple and covers both openings, while dedicated left and right espagnolette window handles allow a more shaped, decorative design and can improve clearance where a straight lever would sit awkwardly against the frame.

Sizing is the most important part of choosing espagnolette window handles, and it is where most replacement mistakes happen.

The spindle is the square bar that connects the handle to the gearing. Thickness matters first: most espagnolette window handles use a 7mm spindle, though some ranges use 8mm, so check before ordering. Spindle length then needs to be long enough to reach and engage the bolt through the depth of the sash. Manufacturers offer several lengths, and the more common sizes cover the majority of standard uPVC and timber sashes - if in doubt, measure your existing spindle or ask our team.

Fixing centres are the distance between the two screw holes on the backplate, and they must match the pre-drilled holes in your window or the espagnolette window handles will not sit square. By far the most common fixing centre is 43mm, which is the industry standard on the vast majority of uPVC and aluminium espagnolette window handles, so it is the size you will come across most often. A few ranges use different centres, so it is always worth checking the measurement before you order.

When replacing, measure centre to centre between the two fixings and compare it against the product specification. Match the spindle thickness, spindle length, fixing centres, handing and finish, and the new handle will fit straight onto the existing gearing.

Espagnolette window handles are available in a wide range of finishes and colours to match your existing ironmongery. Popular options include white, matt black, polished chrome and satin chrome, along with polished brass, satin brass, pewter, antique finishes and stainless steel. White remains the classic choice on uPVC windows, while black window handles and chrome uPVC window handles have become increasingly popular on both modern and heritage-style properties. Styles run from plain low profile espagnolette window handles through to traditional monkey tail designs for period and cottage-style homes.

We supply window hardware from some of the UK's leading names, including Carlisle Brass, Heritage Brass (M. Marcus), Zoo Hardware, From The Anvil, ERA and Fab and Fix, as well as premium British manufacturers such as Samuel Heath, Frank Allart, Croft Hardware and Kirkpatrick. That spread lets you match espagnolette window handles to everything from a new-build uPVC installation to a restored timber sash, all as part of our wider architectural ironmongery range.

Worn, stiff or broken handles are one of the most common window repairs, and the good news is that replacing espagnolette window handles is straightforward.

Yes. In most cases replacing espagnolette window handles is a two-screw job, and you do not usually need to touch the gearing itself. A typical replacement runs as follows:

1. Open the window and pop off the cover caps to expose the two fixing screws.
2. Remove the screws and withdraw the old handle and spindle.
3. Check the spindle thickness and length, then fit the matching replacement.
4. Screw down, refit the caps and test the lever locks and unlocks smoothly.

The only real skill is in the measuring. Before ordering, match the handle to your window on five points:

• Spindle thickness - usually 7mm, sometimes 8mm.
• Spindle length - long enough to engage the bolt through the sash.
• Fixing centres - the distance between the two screw holes.
• Handing - straight, left hand or right hand.
• Finish - to match your existing ironmongery.

A common misunderstanding is worth clearing up: the night vent function is not part of the handle. Night vent is provided by a special keep on the frame that lets the window rest slightly open in a locked, secure position for ventilation. So if you want night vent, you change or add the keep - the espagnolette window handles themselves stay the same.

Besides the espagnolette window handles and bolt, an espagnolette window usually runs on friction hinges (also called friction stays), which let the sash hold open at any angle without a separate stay. If yours are tired or the window will not stay put, browse our friction hinges alongside your new handle.

It helps to understand how espagnolette window handles differ from traditional casement hardware. A classic timber casement is held shut by a separate cockspur handle or window fastener and propped open with a casement stay - two or three separate items working at a single point. An espagnolette system replaces all of that with one lever driving a multi-point bolt, locking the window along its full edge. The espagnolette approach gives better weather sealing and security, which is why it dominates modern glazing, while traditional casement hardware remains popular for authentic period joinery.
