Door loops provide a safe and protected route for electrical cables between the fixed door frame and the moving door leaf. They are commonly used on access control and door entry installations where power or monitoring cables need to connect to equipment mounted directly on the door.

At Door Access Supplies, we stock a range of door cable loops for commercial access control installations, including armoured metal door loops, concealed door loops and matt black options. Available in several lengths, our range is suitable for new installations, retrofit projects and replacement work.

What Are Door Loops Used For?

When an electrical locking device is fitted to a moving door, its cable needs to travel safely from the frame without being trapped, stretched or left exposed. A door loop protects the wiring while allowing the door to open and close normally.

Door loops are often used with:

• Electric locks and electronic locking devices
• Access control and door entry systems
• Solenoid bolts and motorised locks
• Electric panic hardware
• Door monitoring contacts
• Powered handles and door-mounted equipment

Armoured Metal Door Loops

Armoured door loops use flexible metal conduit to protect cables as they pass between the frame and door. They are a dependable choice for commercial access control installations where wiring may be exposed to repeated movement or accidental damage.

Our collection includes 450mm and 600mm armoured metal door loops, as well as a 400mm metal door loop with plastic end fittings. Surface-mounted loops are particularly useful for retrofit installations where routing cables internally through the door and frame is not practical.

They can be used alongside electric strikes, electronic bolts and other powered locking equipment.

Concealed Door Loops

A concealed door loop provides a neater cable-transfer solution, with the main body fitted within the door and frame. This reduces visible hardware and helps create a cleaner finish on offices, managed buildings and modern commercial interiors.

Our concealed door loops are available in 300mm and 500mm versions. Before installation, check that the door and frame have enough internal space for the loop body, cable and full range of movement.

Matt Black Door Loops

For doors fitted with black architectural ironmongery, our matt black armoured door loops offer a coordinated alternative to a standard metallic finish.

Available in 450mm and 600mm lengths, they work well with dark aluminium frames, black door furniture and products from our matt black access control collection.

Choosing the Correct Door Loop

When selecting a door loop, consider the distance between the door-mounted equipment and the frame, the door opening angle, the number of cables required and whether a surface-mounted or concealed installation is preferred.

You should also check:

• The available cable capacity
• The flexibility and diameter of the cable
• The door and frame material
• The required loop length
• The level of mechanical protection needed
• The preferred finish

The loop should move freely throughout the full door-opening cycle without becoming stretched, crushed or trapped.

Complete Your Access Control Installation

Door loops are normally installed as part of a wider electronic access control system. Depending on the application, you may also require maglocks, keypads and fob readers, request-to-exit devices, emergency break glass units and a suitable access control power supply.
