Introduction to the CDVI GF60 Armoured Door Loop and Key Features
CDVI GF60 — 600 mm armoured door loop for external doorsis a purpose-built solution for protecting access-control cabling where a door leaf moves against a fixed frame. Designed for commercial, institutional and high-risk environments, the GF60 combines a stainless-steel armoured tube with vandal‑resistant fixings and robust end caps to create a secure, long-lasting cable transfer point between the door frame and the moving leaf.
Key features at a glance:
- 600 mm stainless-steel armoured loop for external doors.
- Approximately 9 mm internal diameter (sized for common lock, intercom and control cables) and ~13 mm external loop diameter.
- Diax® anti‑vandal fixings and Zamak / cast aluminium end caps for enhanced mechanical protection.
- Surface-mount design for straightforward installation on most door assemblies.
- Lightweight (approx. 0.26 kg) yet robust construction suitable for frequent use and harsh conditions.
Detailed Specifications and Benefits
The GF60 is engineered to address a specific and recurring weak point in access-control installations: the exposed cable run between door frame and leaf. By encapsulating wiring in a stainless-steel armoured loop and terminating it with secure end caps and anti‑vandal fixings, this product reduces the risk of tampering, accidental damage and water ingress to wiring systems that control electric strikes, maglocks, intercoms and door contacts.

The 9 mm internal diameter is a pragmatic choice: it accommodates the typical bundle of low-voltage control and signal cables used for electric strikes, magnetic locks, door position switches and intercom handsets without excessive bending. The 600 mm loop length provides generous slack and routing space while remaining compact enough to fit most door assemblies. Stainless steel offers durable mechanical protection and corrosion resistance for external use, and the Diax® anti‑vandal fixings raise the bar for tamper resistance compared with standard screws. Zamak/cast aluminium end caps provide a rigid enclosure for the anchorage and conceal the fixing points, improving both security and aesthetics.
Use Cases and Scenarios Where the GF60 Excels
The CDVI GF60 is especially well-suited to environments where both security and reliability are required. Typical applications include:
- Commercial office buildings:protecting badge reader, maglock and strike wiring on external access points that receive frequent foot traffic and occasional rough handling.
- Education and healthcare facilities:safeguarding intercom and door-control wiring in high-traffic public areas where vandalism or accidental damage can cause critical downtime.
- Retail and hospitality:protecting wiring for access-control devices on delivery and staff-only doors that may be exposed to harsher handling.
- Industrial and utility sites:securing cable runs in outdoor gates, security booths or plant-room access doors where exposure to weather and mechanical stress is a concern.
- High-risk or public infrastructure:stations, municipal buildings and other installations where vandal‑resistant hardware is specified for compliance or insurance reasons.
Because it is surface-mount and relatively lightweight, the GF60 is also convenient for retrofit projects where replacing or re-routing embedded wiring is impractical. Installers can surface-mount the caps and loop with the Diax® fixings to provide immediate protection without major door modification.
Comparisons with Similar Products on the Market
Armoured door loops are a common accessory in security and door-control systems, but they vary significantly in materials, fixing methods and dimensions. Here’s how the CDVI GF60 typically compares:
- Material and durability:Many budget loops use plated or thin-gauge steel that can corrode or deform over time. The GF60’s stainless-steel loop and metal end caps (Zamak / cast aluminium) offer superior corrosion resistance and mechanical strength suitable for external use.
- Vandal-resistance:The inclusion of Diax® anti‑vandal fixings is a step above generic self-tapping screws seen on lower-cost loops. This reduces the likelihood of tampering or removal by non‑specialist attackers.
- Internal diameter:A 9 mm minimum inner bore is appropriate for modern access-control cabling. Some competitor loops advertise larger bores but sacrifice form factor or durability; others have smaller bores that require cable thinning or bundling which complicates installation.
- Length options:The GF60’s 600 mm length is a common and versatile size. If installations require shorter or longer loops, some suppliers provide multiple lengths; however, the GF60 balances slack with a compact profile that suits most door geometries.
- Price versus performance:The GF60 sits in the mid-range: it commands a premium over basic loops due to the vandal-resistant fixings and metal caps, but it is more affordable than fully sealed or bespoke cable-transit assemblies designed for extreme environments.
When specifying a door loop, it’s important to weigh the expected exposure to vandalism, weather resistance needs, and cable capacity. For standard to moderately hostile external locations, the GF60 offers a balanced specification and cost-effective solution.
Customer Feedback and Installer Observations
No verified customer testimonials were provided with the product data. However, typical feedback themes from installers and contractors who choose armoured loops like the GF60 generally include:
- Appreciation for the sturdiness and professional appearance compared with simple plastic or thin metal loops.
- Positive notes on the ease of retrofit installation due to the surface-mount design.
- Preference for anti‑vandal fixings that increase confidence in installations at remote or publicly accessible doors.
Representative anonymised installer comments (for illustration only):
- "Solid build and quick to fit — saves reworking cables when upgrading an old site."
- "The Diax fixings make a real difference in high-traffic entrances; less maintenance later."
- "Good internal bore for routing intercom and strike wiring without stress on the conductors."
