In this article, we explore everything you need to know about telephone boxes — types, applications, specifications, installation tips, and why the 7035 Rexton telephone box is one of the most trusted choices for electrical professionals in the UAE.
What is a Telephone Box?
A telephone box — also referred to as a telephone outlet box or telephone back box — 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
Types of Telephone Boxes
There are three primary types of telephone boxes used in electrical installations, each suited to specific construction and design requirements:
1. Telephone Box Flush
A telephone box flush — also known as a flush-mounted telephone box — 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.
Key Features:
- 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
Best For:
- Residential villas and apartments
- Corporate office fit-outs
- Hotels and hospitality projects
- Healthcare facilities
- Any application where aesthetics are a priority
Installation Notes: 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
A telephone box recessed 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.
Key Features:
- 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
Best For:
- 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: 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.
3. Telephone Box Surface
A telephone box surface — also known as a surface-mounted telephone box — 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.
Key Features:
- 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
Best For:
- 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: 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.

Applications of Telephone Boxes in UAE Projects
Telephone boxes are an essential component across a wide range of project types in the UAE:
🏠 Residential Projects
In villas and apartments, telephone boxes are installed in living rooms, bedrooms, home offices, and utility areas to provide telephone and data connection points. Flush and recessed telephone boxes are preferred for their clean appearance in residential interiors.
🏢 Commercial & Corporate Offices
Office fit-outs require telephone boxes at every workstation, meeting room, and reception area. Double gang flush telephone boxes are commonly used in commercial spaces to accommodate both telephone and data connections at a single point.
🏨 Hotels & Hospitality
Hotels require telephone boxes in every guest room, lobby, conference room, and back-of-house area. Recessed telephone boxes are preferred in premium hotel rooms for their sleek, high-end appearance.
🏥 Healthcare Facilities
Hospitals and clinics require telephone and data connection points in patient rooms, nursing stations, consultation rooms, and administrative areas. Surface-mounted telephone boxes are often used in clinical areas for easy access and cleaning.
🏭 Industrial & Warehouses
Industrial facilities and warehouses require surface-mounted telephone boxes that are robust, easily accessible, and resistant to dust and mechanical damage. The 7035 Rexton surface telephone box is ideal for these environments.
🏫 Educational Institutions
Schools and universities require telephone and data connection points in classrooms, libraries, administrative offices, and staff rooms. Flush telephone boxes provide a neat solution for educational environments.
🏗️ Infrastructure & Government Projects
Government buildings, airports, and public infrastructure projects require telephone boxes that comply with UAE standards and specifications. The 7035 Rexton range meets these requirements across all installation types.
Installation Guide — Telephone Box Best Practices
Step 1 — 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 — 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 — typically 300mm from the finished floor level for standard installations.
Step 3 — 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 — 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 — typically 150–200mm of spare cable.
Step 5 — Fix the Box
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 — 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 — 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 — Test the Connection
After installation, test each telephone point using a cable tester or telephone handset to verify correct wiring, continuity, and signal quality.

Q: What depth telephone box do I need? The depth depends on the type of socket plate and the amount of cable to be housed inside the box. Standard depths are 25mm for shallow installations, 35mm for standard use, and 47mm for deeper cable management requirements.
