Wall mounted extension leads: mounting options and applications
A wall mounted extension lead provides easily accessible power sockets without having to leave the extension lead loose on the floor or work surface. Depending on the model, extension leads can be mounted on walls, underneath desks, on workbenches or on other suitable surfaces.
Mounting an extension lead can help organise cables, keep sockets within easy reach and reduce loose cables around the workplace. Different mounting systems are available depending on the product, including screw holes, mounting plates, clamps or other fastening solutions.
Why mount an extension lead?
An extension lead is often placed on the floor, behind furniture or underneath a desk. While this may provide the required sockets, it can make plugs difficult to reach and leave cables lying around the surrounding area.
A mountable extension lead can provide several advantages:
- power sockets remain easily accessible
- the extension lead has a defined position
- cables can be organised more clearly
- the extension lead does not slide around on a desk or work surface
- loose cables and extension leads on the floor can be reduced
- the available space on desks and work surfaces can be used more efficiently
Where can an extension lead be mounted?
The suitable mounting position depends on the extension lead, the fastening system and the intended application.
Typical locations include:
- on a wall
- underneath a desk
- on the side or underside of furniture
- on a workbench
- on or underneath a work surface
- in workshops or garages
The extension lead should always be mounted in a position where the sockets and switches remain accessible and where the cable is not stretched, crushed or exposed to mechanical damage.
How can an extension lead be mounted on a wall?
Some extension leads are designed with integrated fastening points or screw holes. These allow the housing to be fixed to a suitable surface using the mounting method intended for the product.
Other models use a separate mounting plate. The plate is first attached to the required surface and the extension lead is then secured to the mounting system.
Always follow the mounting instructions supplied with the individual extension lead. The correct fixing method also depends on the surface to which the product is being attached.
Can an extension lead be mounted underneath a desk?
Yes, if the extension lead and its mounting system are designed for this purpose. Installing an extension lead underneath a desk can be particularly practical in home offices and workplaces because plugs and cables can be kept away from the main work surface.
When choosing the position, make sure that:
- plugs can still be inserted and removed easily
- the on/off switch remains accessible if required
- large power adapters have enough space
- the mains cable is not stretched or trapped
- the extension lead is not covered by materials that could restrict heat dissipation
Further ideas for supplying power around a desk are covered in Extension leads for the home office.
Can I mount an extension lead without drilling?
Depending on the product, an extension lead may also be mounted without drilling. Some models are designed for use with mounting plates, clamps, adhesive fastening systems or other product-specific solutions.
Whether these methods are suitable depends on the extension lead and the surface. Only use a fastening method that is intended for the product and capable of holding it securely together with the connected cables and plugs.
Clamp-mounted solutions can be particularly useful on desks or work surfaces where permanent drilling is not desired.
Extension leads with a removable mounting plate
A removable mounting plate can make it easier to install an extension lead in a fixed position. Depending on the product design, the plate is mounted first and the extension lead is then attached to it.
This can be useful where the extension lead needs to be removed temporarily while the mounting points remain in place.
Selected aluminium extension leads use dedicated mounting systems for installation on walls, desks or work surfaces. The installation principle is explained in Mounting brennenstuhl® Premium-Alu-Line extension leads.
Wall mounted extension leads for desks and home offices
Mounting an extension lead at or underneath a desk can provide easy access to power for monitors, computers, chargers, lamps and other workplace equipment.
When several devices are connected, also consider the arrangement of the sockets. Sufficient spacing can be useful for larger plugs and external power supplies that might otherwise block neighbouring outlets.
Depending on the application, additional features such as individual switches, USB charging or surge protection may also be useful.
Wall mounted extension leads for workshops and workbenches
A fixed extension lead can also be useful at a workbench or in a workshop where electrical devices are regularly connected in the same location.
The extension lead must be suitable for the intended environment. Factors such as dust, moisture, mechanical stress and the required electrical load should be considered when choosing a product.
A standard extension lead intended for indoor use should not automatically be used in environments that require additional protection.
Can an outdoor extension lead be wall mounted?
Some extension leads designed for outdoor or more demanding environments also provide mounting options. However, suitability for wall mounting and suitability for outdoor use are separate product characteristics.
For outdoor applications, always check whether the individual product is designed for the intended environmental conditions and has the appropriate protection rating.
More information on choosing a suitable product is available in Outdoor extension leads.
What should I look for when choosing a wall mounted extension lead?
Before choosing a mountable extension lead, consider the following factors:
- Mounting system: Check whether the extension lead uses screw holes, a mounting plate, clamps or another fastening method.
- Mounting position: Make sure the sockets, plugs and switches remain accessible after installation.
- Number of sockets: Choose enough outlets for the devices that regularly need to be connected.
- Socket arrangement: Consider the space required by large plugs and power adapters.
- Cable length: The mains cable should comfortably reach the wall socket without being stretched.
- Maximum electrical load: The combined power consumption of connected devices must remain within the rating specified for the individual extension lead.
- Environment: Choose a product suitable for the location and operating conditions.
- Additional functions: Depending on the application, switches, USB charging or surge protection may also be useful.
How do I organise cables around a mounted extension lead?
Mounting the extension lead is only one part of cable organisation. Power cables can also be routed so that they do not hang loosely across work surfaces or walkways.
Suitable cable management systems can help guide excess cable and keep individual cables together. Make sure that cables are not tightly bent, crushed, trapped behind furniture or exposed to unnecessary mechanical stress.
Is it safe to mount an extension lead permanently?
A mountable extension lead can remain in a fixed position when the product is designed for mounting and is installed according to the manufacturer's instructions.
Even when mounted permanently, the extension lead should remain accessible for inspection. Regularly check the plug, cable, housing and sockets for visible damage and make sure that connected devices do not exceed the maximum electrical load of the product.
A wall mounted or desk mounted extension lead can therefore be a practical solution wherever several sockets are regularly required in the same location.
