Introduction to the CDVI FLEX-60 600 mm Compact Door Loop
CDVI FLEX-60 600 mm Compact Door Loop (F0524000015)is a purpose-built cable transition designed to protect and guide electrical and signal cables between a fixed door frame and a moving leaf. Intended primarily for access control, intercom and electric locking systems, the FLEX-60 combines a stainless-steel spiral tube with cast Zamak end caps and concealed fixings to provide a neat, vandal-resistant solution. At a suggested price point that makes it accessible to installers and specifiers, the FLEX-60 is positioned as a durable, compact alternative to bulkier conduit systems.
Key features at a glance
- 600 mm compact loop length suitable for most single-leaf doors
- Stainless-steel spiral tube for wear and tamper resistance
- Cast Zamak end caps with concealed fixings for a clean appearance
- Internal diameter of approximately 7 mm — fits typical lock, reader and power cables
- Surface-mount installation that is quick and straightforward for retrofit or new-builds
- Commonly reported 2-year limited warranty and CE / RoHS markings (confirm with supplier)
Detailed description: specifications and practical benefits
The FLEX-60 is engineered around a stainless-steel spiral tube with an external diameter in the region of 10.5–10.6 mm and an internal diameter of about 7 mm. This gives installers a reliable path for low-voltage cables used with electric strikes, magnetic locks, proximity readers and door sensors. The compact 600 mm loop length is typically long enough to accommodate full range of motion on standard single-leaf doors while remaining discrete and unobtrusive.
Durability is a core benefit. The stainless-steel spiral tube resists abrasion caused by repeated door movement and is less vulnerable to cutting or tampering than plastic alternatives. The end caps are cast from Zamak, a family of zinc-aluminium alloys known for good mechanical strength and corrosion resistance; these end caps conceal fixings for an aesthetically pleasing finish and to further deter tampering.
- Loop length: 600 mm — appropriate for most single doors
- Internal diameter: approximately 7 mm — suitable for multiple low-voltage cables (locks, readers, power)
- External tube diameter: ~10.5–10.6 mm
- Cap dimensions: approx. 30–35 mm height/width depending on the listing
- Weight: around 140 g — light enough to mount without heavy-duty supports
These dimensions make the FLEX-60 a compact option that fits discrete installations where bulky conduit would be visually disruptive or impractical. Because the internal diameter is limited to roughly 7 mm, installers should plan cable selection and bundling accordingly; multiple thin signal cables and small power leads typically fit easily, but large multi-core power cables may not.
Distributor listings commonly report CE and RoHS marking and a 2-year limited warranty. As approvals and warranty terms can vary by supplier and region, confirm exact certifications and coverage with the vendor before installation. For fire doors and other certified assemblies, check with the door manufacturer whether the loop and mounting method affect the door’s certification.
Use cases and scenarios where the FLEX-60 excels
The FLEX-60 is ideal for installations where a clean, durable and compact cable transition is required. Typical use cases include:
- Access control systems: routing cables for magnetic locks, electric strikes, and door position switches while protecting wiring against wear and tampering.
- Reader installations: providing a tidy and secure path for proximity, biometric or keypad reader cables mounted on the door leaf.
- Intercom and audio systems: protecting microphone, speaker and power cables in residential or commercial entry systems.
- Retrofit projects: surface-mount design with concealed fixings makes the FLEX-60 a fast and neat solution when upgrading older doors without cutting through frames.
- High-traffic public locations: stainless-steel construction and secure end caps resist vandalism and reduce maintenance over time.
Because the loop is compact, it works particularly well in environments where aesthetics matter — reception areas, offices, schools and retail premises — or where limited clearance between frame and leaf prevents bulkier conduits from being used.
Comparisons with similar products on the market
When evaluating the FLEX-60 against alternative cable transition options, consider the following common competitors: plastic flexible conduits, heavy-duty articulated arm loops, and integrated hinge-based cable solutions.
Plastic flexible conduits (PVC or nylon) are lightweight and inexpensive, but they are more vulnerable to abrasion, UV degradation and intentional cutting. The FLEX-60’s stainless-steel spiral tube offers better mechanical protection and a more premium appearance, which is often preferable in commercial or public-facing installations.
Articulated arm loops and longer drop loops provide greater cable capacity and flexibility for double doors or oversized openings. However, for single-leaf doors where cable requirements are modest, the compact 600 mm FLEX-60 reduces visual bulk and simplifies installation. If a project requires routing many cables or thicker bundles, a larger-diameter solution might be more appropriate.
Zamak end caps give a more robust and tamper-resistant termination compared with plastic end caps and exposed screws. They also improve aesthetics. Some specialty solutions use concealed hinge-integrated channels that can be more subtle but may be more expensive or require specific door hardware compatibility. FLEX-60 hits a balance between security, cost and ease of retrofit.
Customer feedback and installer insights
While individual testimonials vary, reseller listings and installer forums commonly highlight a few recurring points of feedback:
- Installers appreciate the compact size and clean finish — it integrates well with modern door hardware without looking bulky.
- The stainless-steel tube and metal end caps are frequently called out as a clear advantage in high-traffic or public-facing locations where durability matters.
- Some installers note the internal diameter requires careful cable planning; multiple thin cables are fine, but larger power cables can be tight or require staging during installation.
- Resellers often mention a standard two-year limited warranty and CE/RoHS markings; however, installers recommend confirming approvals for any regulated or fire-rated doors.
If you need concrete, attributable customer reviews for marketing or procurement, request review samples or ask your supplier for references — many distributors can share case studies or installer feedback for similar projects.
Installation and practical considerations
Installation is surface-mounted between the frame and door leaf. Best practices include routing cables without sharp bends, avoiding crushing during fitment, and testing cable continuity and door operation before completing the installation. For any fire-rated door, confirm that adding a surface-mounted loop will not invalidate fire certification.
Because the FLEX-60 is a compact solution, it’s ideal for retrofits where minimal alteration to the door or frame is desired. Use appropriate fasteners per the door/frame material and follow the manufacturer’s installation guidance.
Conclusion: why the CDVI FLEX-60 is a solid choice
The CDVI FLEX-60 600 mm compact door loop offers a practical blend of durability, discreet appearance and installer-friendly design. Its stainless-steel spiral tube and Zamak end caps deliver robust protection against wear and tampering, while the concealed-fixing, surface-mount design keeps the installation neat. For most single-leaf doors used in access control, intercom and locking applications, the FLEX-60 provides ample cable capacity with a clean aesthetic and a competitive price point.
Before purchase, confirm approval and warranty details with your supplier and verify suitability for fire-rated doors if applicable. When used in the right scenarios — retrofit jobs, commercial entrances, schools, and retail spaces — the FLEX-60 stands out as a dependable, low-profile cable transition that reduces maintenance risk and improves the visual finish of door hardware installations.
