Advisor: Questions you should deal with before buying lockable window handles

What do lockable window handles do?

Lockable window handles are mainly used for safety from danger, as they allow windows to be locked firmly.

With the corresponding key they can be locked like an outer door.

This distinguishes them from conventional window handles, as they do not have a lock for locking. This makes them particularly useful as burglar or child protection.

So if you are thinking about protecting your house or your children better from danger, lockable window handles are a very useful tool.

Some handles even have a built-in alarm function which, for example, emits an acoustic signal in the event of a possible burglary in order to chase potential burglars away.

How useful are lockable window handles?

As was made clear before, lockable window handles in households can protect children from possible dangers that lie outside the window.
If you live in a region where there are a lot of break-ins, you are better protected with a lockable window handle.
These can also have a built-in alarm function. It is best to install lockable window handles in these places:

Ground floor windows
French doors
patio doors

It is also important to install burglary protection on front doors.

How secure are lockable window handles?

Burglary protection
Note: It should be noted that lockable window handles in general cannot guarantee absolute safety from danger.

They can mainly be used to reduce these dangers, but not completely exclude them. This applies mainly against burglary. Therefore, they are also considered more as a burglar-resistant instrument.

Why? Windows could still be smashed, but most burglars want to cause as little disturbance as possible.
Loud noises would immediately be heard by neighbours. The burglary attempt would have failed immediately.

For this reason, a so-called glass grip is usually used for burglaries.

During this process, only a small area of the glass pane near the window handle is broken in order to get to the window handle.

This has already opened many windows. A locked handle would prevent this.

Child protection

On the other hand, they are an excellent child protection, provided the children do not get their hands on the key to the lock.

Especially if you live in an apartment on a floor higher than the ground floor.

Why? Unattended, children could open the window and, in the worst case, fall out. The resulting consequences could be disastrous.

The most important thing to remember is to keep the key safe. So that the children can’t find it by accident.

What should you pay attention to with lockable window handles?

If you want to get a lockable window handle, you should consider whether you also meet the other necessary security measures.
In addition to the lockable window handles there are two other tools which increase the window security even more.
Mushroom head cones and window security foils. Are also two other efficient tools that you should retrofit to further optimize security.
A normal window normally has no resistance class. With these additional measures, in addition to the lockable window handles, you can further increase your security, to the standard of class RC2.
Further resistance classes are listed below as an overview.
The number of minutes is a guideline for the average time a burglar needs to open the window from the outside according to the respective resistance class.
Resistance classes
A resistance class of a window indicates how well it is secured on the lock and hinge side. RC stands for Resistance Class.

The higher the number, the more secure the class is against burglars. The classification of resistance classes has been Europeanised since 2011.

If you search online for windows you can usually find the RC value in the item description.

In the following video, which was produced by the company Aldra, you can watch another example of a levering attempt of an RC2 window.

It becomes clear how difficult it is to crack a class 2 security window:

The following comparison shows how the costs differ depending on the material of the window handle.
Lockable window handles are often offered in sets, therefore the unit price was taken into account here

For aluminium materials the prices start in a very affordable single digit range (about 8€).

Handles made of stainless steel are on average somewhat more expensive than the aluminium version. Nevertheless, they start in the low 2-digit price segment (approx. 15).

In addition to their appearance, the two materials also differ in their weight, as aluminium is on average one-third lighter than stainless steel.

Both fabrics have a long durability nevertheless. In the question of alternative to lockable window handles, the differences between the two types of material are discussed in more detail.

What alternatives are there to lockable window handles?

There are also other types of window security that you should know about. For one, a normal alarm system can be installed.
But there are also lockable window handles that have an additional alarm function, which cost a little more than the normal version.

You can also have a grille installed from the outside to protect your children. This should further reduce the chance of an accident.

Decision: What types of lockable window handles are available and which one is right for you?

If you want to buy a lockable window handle, there are usually two types you can choose from.

  • Lockable window handle in aluminium
  • Lockable window handle in stainless steel

There are also lockable window handles made of brass, but these are not as numerous as the other two types on the market.

The different types each have advantages and disadvantages. Depending on what you prefer, a different species is suitable for you. With the following section we would like to make the decision easier for you.

What distinguishes lockable aluminium window handles and what are the advantages and disadvantages?

An aluminium handle is usually cheaper than all other materials because it is a light metal. They are most often offered for security windows in the trade.

In tests, the aluminium version often comes out on top and does not rust, so you are on the safe side when buying.


No rust


Design less high quality

However, there is the possibility that condensation water can accumulate on the handle. Also the handle often does not look very noble.

What distinguishes lockable stainless steel window handles and what are the advantages and disadvantages?

A stainless steel handle is usually more expensive than aluminium. They are also often offered for security windows in the trade.

They usually have a higher quality design than the aluminium version. In tests, the stainless steel variant also scores less than the test winners, as lockable window handles made of aluminium.


High quality design


Material is heavier

Stainless steel can be more prone to rust. In addition, the weight can cause problems when mounting the handle.

Purchase criteria: You can compare and evaluate lockable window handles based on these factors

Now we would like to show you which criteria can be decisive for you when buying a lockable window handle.

You can use the following criteria concerning the product to better compare the handles:

  • The alarm function
  • The resistance
  • The material
  • The length of the square spindle
  • The parental lock
  • The color

In the following we will explain to you what you should pay attention to with the individual criteria mentioned.

The alarm function

First and foremost, lockable window handles provide mechanical security. However, a very useful addition is an alarm function.

Not every lockable window handle has such a function. It offers an additional deterrent effect against possible burglars.

Loud noises help to chase the burglars away, because otherwise they would be discovered faster.

Since Abus is apparently the only manufacturer that offers devices with an alarm system, such handles are not very widespread on the market.

In addition, an additional surcharge is to be expected for such a function.

The resistance

The most important criterion that should fulfil the purpose of lockable window handles at all is resistance.

What good is a great design if the actual function cannot be fulfilled.

You can recognize the quality of a lockable window handle by the already mentioned resistance class.

A resistance of 100Nm is generally recommended.

Of course there are also higher resistors such as 200Nm, which as a result offer a higher protection factor than lower values.

You should also take a look at the tests and decide what is the best value for money for your budget.

Because a particularly high level of burglary resistance can also affect the price.

The material

Lockable window handles can be made of different materials

In the following we would like to introduce these once, so that you keep a better overview, whether and how important the material of a lockable window handle could be for you.

Besides the most common materials such as aluminium and stainless steel, there are also lockable window handles, which are also made of brass.

In addition to their appearance, they also differ in terms of wear and tear.

It turns out that the aluminium lockable window handle is superior in properties such as weight and susceptibility to corrosion.

The robustness, i.e. the resistance to external forces, can be attributed more to the manufacturer’s manufacturing quality than to the material.

The length of the square spindle

In Germany there are 4 different formats of quadrangular sticks. Besides window handles, they are also used in room, house and fire protection doors.

A common square spindle format for window handles is 7mm, which may vary in other countries.

But since not every square pin fits every window, there are also lockable window handles that have a universally adjustable square pin.

This allows the pen to adapt individually to each window. Thus there are fewer difficulties during installation.

The parental lock

Lockable window handles are also often used as child locks.

Since it is no longer possible to open the window after it has been closed, such a handle can be used as such a safety device.

Especially useful if you live in an apartment on a higher floor, for example.

But of course there is one thing you should keep in mind. It is important to make sure you do not leave your keys lying around.

Otherwise the children might try to open the window with the key they found.

If you want more information on how to store the key, you can look at the trivia section below, which answers the question “Where to put the key?

The color

Lockable window handles are also available in a variety of different colours which are offered in the trade.

If you have a particular window frame design, there is also a matching color as with traditional window handles.

This applies if you want to attach importance to the appearance of your windows. The most common colours are here:

  • White
  • Silver
  • Bronze

There are also colours like black, brown or gold. However, these are not as common as the colours mentioned above.

Trivia: Worth knowing facts around the topic abschließba

How to install lockable window handles?

A lockable window handle is very popular against burglary protection.

The rather simple assembly makes it easy to install even for people who are less skilled.

To make this even more vivid, you will find here a video of the company tectake, what the components of a lockable window handle are.

Since one usually replaces a conventional window handle with a lockable window handle, the short description of the installation follows:

    Turn the cover plate behind the handle by 90 degrees.
    Using a screwdriver, loosen the screws of the previous window handle.
    Pull off the old handle.
    Put on the new handle and screw it back on
    Turn cover plate to old position

After successful installation, nothing more needs to be done except to lock the handle with the corresponding key as required.

Where do I put the key?

One thing to consider is how to store the key. Because that’s still a problem when you have particularly young children.

At best, the key should be stored near the lock out of the reach and sight of children.

There is no general solution, because every household is different. So you can give your creativity free rein.
