Introduction to the CDVI GF45 450 mm Armoured Door Loop
CDVI GF45 450 mm Armoured Door Loop (Ref F0524000004)is a compact, robust solution for routing and protecting cables between a fixed door frame and a moving door leaf. Designed primarily for access-control and locking installations, the GF45 combines a stainless-steel spiral loop with ZamakAE die-cast end caps to deliver a vandal-resistant, corrosion-resistant cable transfer system. At 450 mm long with a minimum internal bore of 9 mm, it accepts most common lock, sensor and control cables used in commercial and residential doors.

Use cases and scenarios where the GF45 excels
The GF45 is a versatile component for many access-control and door-security projects. Its combination of a mid-length loop, a 9 mm internal bore, and rugged construction makes it a practical choice in the following scenarios:
In environments where electronic locks, door sensors and exit devices are installed on office doors, the GF45 provides a neat and protected path for wiring. Its vandal-resistant finish reduces service calls in high-traffic corridors or public areas.
Retail outlets, restaurants and hotels often have doors that are accessed frequently and are exposed to accidental knocks or deliberate tampering. The GF45E28099s sturdy spiral and metal end caps help protect lock and sensor wiring while maintaining a discreet profile.
For homeowners upgrading to electric strikes, smart locks or connected sensors, the GF45 offers an economical surface-mounted approach where in-frame wiring is not feasible. Its 450 mm length covers most standard offset gaps between frame and leaf without invasive routing.
The productE28099s vandal-resistant design and secure fixing make it suitable for use on doors at schools, hospitals, transport hubs and other locations where tamper risk is higher.
Comparisons with similar products on the market
Armoured door loops come in a range of materials, lengths and price points. When comparing the CDVI GF45 to alternatives, consider the following factors:
Some competitors use flexible plastic conduits or nylon-covered steel. The GF45E28099s stainless-steel spiral is more resistant to cutting and wear than many plastic options, while ZamakAE end caps provide a stronger and more tamper-resistant mounting than thinner stamped metal or plastic caps.
Other door loops are available in shorter or longer lengths and with larger bores (for bulkier cable bundles). The GF45E28099s 450 mm length strikes a balance for most standard doors; installers requiring larger harnesses or wider clearance should consider larger-bore models or longer loops where available.
Surface-mounted loops are generally easier and faster to fit than recessed or in-frame options. The GF45E28099s supplied end caps and fixing hole pattern keep installation straightforward. Higher-end models may offer integrated cable grommets or snap-fit caps for faster serviceability, but these can add cost.
Positioned as an economical option within CDVIE28099s range (recommended retail around A313.79), the GF45 competes well on price-to-durability for everyday access-control installations. Premium alternatives with heavier-duty finishes or larger bores will cost more but may be justified in specialist or extreme environments.
Customer feedback and installer observations
Direct customer testimonials specific to this reference are limited in public listings, but common installer feedback on similar CDVI door-loop products highlights a few recurring themes:
- Reliability:Installers often praise the solid feel of the end caps and the durability of the spiral, noting fewer damage-related callouts compared to cheaper plastic alternatives.
- Fit and finish:The compact footprint of the end caps and the neutral metallic finish fit well with commercial door aesthetics.
- Value:For projects needing dependable cable protection without the higher expense of heavy-duty or custom loops, the GF45 is frequently seen as a pragmatic choice.
If you require verified user reviews, check reseller listings and installer forums where the EAN (3662211005839) and part reference (F0524000004) are used; many suppliers include customer ratings and project notes that can help validate suitability for specific installations.
Installation, compliance and best practices
Installation should follow the CDVI datasheet and manual for correct fixing, cable routing and any specified torque or sealing requirements. While the GF45 provides mechanical protection, you should also ensure electrical and fire-safety guidance is followed for cable types, segregation and grommeting. Where local regulations require certification (CE / UKCA or equivalent), refer to the manufacturer documentation to confirm applicable approvals for your market. Always have installations performed or inspected by a qualified installer.
Conclusion: Why the GF45 is a solid choice
The CDVI GF45 450 mm Armoured Door Loop is a practical, cost-effective solution for protecting and routing lock and control cables on doors.
