In this article, we explore everything you need to know about telephone boxes ā types, applications, specifications, installation tips, and why theĀ 7035 RextonĀ telephone box is one of the most trusted choices for electrical professionals in the UAE.
AĀ telephone boxĀ ā also referred to as a telephone outlet box or telephone back box ā is an electrical enclosure designed to house telephone sockets, data connectors, and communication outlets within walls, ceilings, or surface-mounted positions.
Telephone boxes are an essential component of any structured cabling or telecommunications installation, providing a secure, neat, and accessible housing for telephone and data connection points in homes, offices, hotels, hospitals, and industrial facilities.
Key Functions of a Telephone Box:
Houses telephone sockets and data connectors securely
Provides a neat and professional finish to telephone points
Protects internal wiring and connections from damage
Allows easy access for maintenance and upgrades
Supports organized cable management within walls and surfaces
There are three primary types of telephone boxes used in electrical installations, each suited to specific construction and design requirements:
AĀ telephone box flushĀ ā also known as a flush-mounted telephone box ā is installed directly into the wall so that the front face of the box sits level with the wall surface. This creates a clean, seamless appearance that is preferred in modern interior design.
Installed inside a cut-out in the wall
Front face sits flush with the wall surface
Clean and professional appearance
Concealed wiring for a neat finish
Available in standard single and double gang sizes
Residential villas and apartments
Corporate office fit-outs
Hotels and hospitality projects
Any application where aesthetics are a priority
Installation Notes:Ā Flush telephone boxes require a wall cut-out to be made during construction or renovation. They are typically installed during the first fix stage of electrical works, with the socket plate fitted during second fix after plastering and painting are complete.
2. Telephone Box Recessed
AĀ telephone box recessedĀ is similar to a flush box but is set slightly deeper into the wall, allowing the socket plate and telephone connector to sit completely within the wall cavity. This provides an even cleaner and more minimalist appearance, with no protrusion from the wall surface whatsoever.
Deeper installation into the wall cavity
Socket plate and connector fully recessed into the wall
Ultra-clean, minimalist appearance
Ideal for feature walls and high-end interior finishes
Provides maximum protection for internal connections
Luxury residential projects
High-end hotel and hospitality interiors
Executive offices and boardrooms
Architectural and designer interior projects
Applications requiring a completely flat wall finish
Installation Notes:Ā Recessed telephone boxes require careful planning and precise wall cutting during the construction phase. They are best installed by experienced electrical contractors to ensure correct depth and alignment with the wall finish.
AĀ telephone box surfaceĀ ā also known as a surface-mounted telephone box ā is installed directly onto the wall surface without any wall cutting or embedding. The box protrudes from the wall and is fully visible, making it the easiest and most cost-effective option to install.
Mounted directly onto the wall surface
No wall cutting or chasing required
Quick and easy installation
Ideal for retrofitting and upgrades
Fully accessible for maintenance and modifications
Industrial and warehouse facilities
Server rooms and data centres
Retrofitting in existing buildings
Temporary or modular installations
Areas where wall cutting is not permitted or practical
Installation Notes:Ā Surface telephone boxes are fixed directly onto the wall using screws or adhesive. Cable entry is typically through knockout holes or cable glands on the back or sides of the box. They are ideal for areas where speed of installation is important or where the building structure does not permit wall chasing.

Installation Guide ā Telephone Box Best Practices
Step 1 ā Plan the Installation
Before installation, identify the exact location of each telephone point based on the electrical layout drawing. Ensure the position complies with UAE DEWA regulations and building standards.
Step 2 ā Mark the Wall Position
Use a pencil and spirit level to accurately mark the position of the telephone box on the wall. Ensure it is at the correct height ā typically 300mm from the finished floor level for standard installations.
Step 3 ā Prepare the Wall (Flush & Recessed)
For flush and recessed telephone boxes, use a chasing tool or angle grinder to cut the wall to the correct size and depth. Remove dust and debris from the cavity before installation.
Step 4 ā Route the Cables
Pull the telephone or data cable through the wall cavity to the installation point. Leave sufficient cable length inside the box for easy termination ā typically 150ā200mm of spare cable.
For flush and recessed boxes, secure the telephone box in the wall cavity using suitable wall plugs and screws. For surface boxes, drill and fix directly onto the wall surface. Ensure the box is perfectly level.
Step 6 ā Terminate the Cable
Connect the telephone or data cable to the appropriate socket plate or connector following the correct wiring standard (T568A or T568B for data, standard BT wiring for telephone).
Step 7 ā Fit the Socket Plate
Attach the telephone socket plate or data outlet to the front of the telephone box using the fixing screws provided. Ensure the plate is flush and level with the wall surface.
Step 8 ā Test the Connection
After installation, test each telephone point using a cable tester or telephone handset to verify correct wiring, continuity, and signal quality.
