CDVI FLEX-30 Compact Stainless Steel Door Loop 30 cm FLEX-30

Introduction to the CDVI FLEX-30 and its key features

CDVI FLEX-30 — Compact door loop for secure cable transfer

The CDVI FLEX-30 is a purpose-built, compact stainless-steel door loop designed to protect and guide cables between a fixed frame and a moving door leaf. At 300 mm (30 cm) in length, the FLEX-30 is sized to suit standard doors where a short, neat cable run is required for access control hardware such as electric strikes, magnetic locks, door sensors and control wiring. Its stainless-steel spiral tube, Zamak® / cast aluminium end caps and concealed fixings deliver an aesthetic, vandal-resistant finish ideal for commercial, residential and light-industrial installations.

Detailed specifications and benefits

The FLEX-30 combines simple, robust construction with installation-friendly detailing. Key specifications include:

• Tube length:300 mm (30 cm), a compact length for tidy door installations.
• Internal diameter:≈ 7 mm — suitable for typical lock and low-voltage control cables.
• External diameter:≈ 10.5 mm, providing a slim profile on door edges.
• Materials:stainless-steel spiral tube for abrasion resistance; Zamak® / cast aluminium end caps with concealed fixings for a neat surface-mount finish.
• Mounting:surface-mount installation with concealed fixings — improves appearance and reduces tampering risk.
• Weight:≈ 0.09 kg — lightweight for easy handling and minimal load on door hardware.
• Manufacturer warranty:10 years (confirm regional terms with supplier).

Benefits of these specifications include:

• Durability:Stainless-steel construction resists abrasion, corrosion and wear from repeated door movement, extending service life compared with non-metallic loops.
• Aesthetics and security:Zamak/cast aluminium end caps with concealed fixings produce a clean, vandal-resistant appearance that reduces tampering opportunities and suits visible door edges in public spaces.
• Compatibility:The ≈7 mm internal bore accommodates common lock and sensor cabling, while the compact 30 cm length is compatible with most standard door-frame geometries.
• Simple installation:Surface-mount design and lightweight construction save time on site. Detailed hole-centres and fixing guidance are available in CDVI’s datasheet and installation manual.
• Cost-effectiveness:With a suggested retail price of 12.99 and a modest supplier cost base, the FLEX-30 offers an economical, long-lived solution for protecting access control cabling.

Installation notes and compliance

Installers should consult the CDVI installation manual and datasheet for precise hole centres, fixing recommendations and wiring instructions. Surface-mount installations must be carried out by a qualified installer or electrician to ensure compliance with building and electrical codes. CDVI provides regional documentation and may list a 10-year guarantee in certain territories — confirm warranty terms and local compliance with your supplier.

Use cases and scenarios where the FLEX-30 excels

The FLEX-30 is engineered for situations where a short, robust, and discreet cable transfer is required between a door leaf and its frame. Typical applications include:

• Access control systems:Protects and routes cables for electric strikes, magnetic locks, keypads, proximity readers and door controllers.
• Door sensors and safety devices:Suitable for reed switches, magnetic contacts and other sensor wiring that require protected runs across moving joints.
• Commercial entrances:Offices, retail units and public buildings where a tidy, vandal-resistant finish and reliable cable protection are needed.
• Residential and light-industrial doors:Ideal for properties that need a compact loop rather than a larger conduit system.
• Automated doors and frequent-use environments:Stainless-steel spiral resists wear in doors with high cycles, reducing maintenance and replacement frequency.

Because of its compact length, the FLEX-30 is particularly suited to inward- or outward-swing standard doors and where minimal visual intrusion is important. For larger doors or where more wiring or greater angular movement is required, longer loops or alternative routing solutions may be more appropriate.

Comparisons with similar products on the market

When choosing a door loop there are several common options: stainless-steel spiral loops like the FLEX-30, plastic or PVC loops, armoured cable conduit and hidden jamb wiring. How does the FLEX-30 compare?

• Stainless-steel spiral vs PVC/plastic loops:Plastic loops are inexpensive and flexible but can wear, crack or discolor over time and are more easily tampered with. The stainless-steel spiral of the FLEX-30 offers superior abrasion resistance, longevity and a more professional appearance, which is important in commercial and high-traffic installations.
• Surface-mount spiral vs armoured conduit:Armoured conduit may offer higher mechanical protection for heavy-duty or exposed installations, but it typically requires more invasive installation and can be bulkier. The FLEX-30 delivers a balance of protection and low visual profile for standard access control applications.
• Short (30 cm) vs longer door loops:The compact 30 cm length is perfect for typical doors and minimizes visible hardware. If your installation requires extended travel, multi-point locks or larger clearances, longer loops or tailored solutions will be needed — CDVI and other manufacturers often supply multiple lengths.
• Concealed fixings vs exposed fixings:Concealed fixings on the FLEX-30 both improve aesthetics and reduce tampering risk compared with devices that use exposed screws or clips.

Overall, the FLEX-30 is positioned as a premium compact option among standard door loops: it provides better material durability and finish than basic plastic loops, while being simpler and less obtrusive than heavier conduit systems.

Customer feedback and installer perspectives

Official public reviews for small, specialist products like the FLEX-30 are often limited, but common installer and integrator feedback themes for stainless-steel spiral door loops include:

• Positive:"Neat finish and robust — looks professional once installed and stands up to regular use." Installers appreciate the concealed fixings and compact profile for front-of-house doors.
• Positive:"Easy to route common lock and sensor cables — internal diameter is adequate for most jobs." The ≈7 mm internal bore suits typical low-voltage access-control wiring without crowding.
• Constructive:"Confirm cable bundles before ordering — if multiple thick cables are needed, a larger bore or longer loop might be required." This is a reminder to check cable diameters and movement requirements on-site.
• Value:Users often note that metal loops like the FLEX-30 justify a slightly higher price than PVC alternatives due to lower maintenance and better appearance over time.

These representative insights reflect typical trade comments and help prospective buyers set realistic expectations for performance and installation planning.

Conclusion: Why the CDVI FLEX-30 is a great choice

The CDVI FLEX-30 is a thoughtfully designed, compact stainless-steel door loop that balances durability, discreet appearance and installation practicality.
