Introduction to the CDVI 500-ZL / 500ZL-AC Z&L Bracket and its key features
TheCDVI 500-ZL / 500ZL-AC Z&L Mounting Bracketis a purpose-built accessory for magnetic locking systems, designed to accommodate surface-mounted maglocks rated at approximately 500 kg holding force. Available in a standard variant and an architectural housing (500ZL-AC) finished in satin anodised aluminium, this bracket lets installers achieve reliable armature alignment while maintaining a neat, professional appearance. Its adjustable depth and surface-mount design make it especially useful for retrofit and commercial installations where inward-opening doors are common.
Key features at a glance
- Compatibility:Built to fit 500 kg (approx.) surface maglocks.
- Finish options:Satin anodised aluminium on the 500ZL-AC for an architectural look; standard 500-ZL for cost-conscious installs.
- Adjustability:Depth adjustable between 50.5 mm and 101 mm to suit varying door/frame clearances.
- Mounting style:Surface-mounted, primarily for inward-opening doors, simplifying installation on existing frames.
- Robust construction:Aluminium body provides corrosion resistance and a lightweight but sturdy platform for heavy-duty maglocks.
Detailed specifications and the benefits they deliver
Manufacturer:CDVI. Part numbers covered:500-ZL(standard) and500ZL-AC(architectural housing). The product type is a surface Z&L mounting bracket engineered for internal installation with maglocks that provide a holding force in the vicinity of 500 kg. The bracket is intended mainly for inward-opening doors where the Z&L arrangement is ideal for positioning the armature plate correctly against the magnet face.
The bracket is manufactured from aluminium and the 500ZL-AC variant is finished in satin anodised aluminium for a subdued silver look that complements modern glass, timber and metal door furniture. The aluminium construction balances low weight with high rigidity and corrosion resistance, making the bracket suitable for commercial environments including offices and reception areas where appearance matters.
Height:265 mm. Width:76 mm. Adjustable depth:50.5–101 mm, allowing installers to adapt to different door stiles and frame clearances. Weight: the 500ZL-AC architectural version is approximately1.65 kg, while the standard 500-ZL variant is lighter at around0.90 kg. These dimensions and weights make the bracket robust enough to hold a 500 kg class maglock while remaining manageable during installation.
The bracket is designed for internal surface maglocks rated at approximately 500 kg; it is essential to verify armature plate dimensions and the specific maglock model before purchase. Two variants—standard and architectural—allow selection based on budget and aesthetic needs. Installation should follow the manufacturer datasheet and templates; the bracket’s surface-mounted approach saves time during retrofits but installers should confirm whether outward-opening doors are supported for their specific maglock model.
Practical benefits for installers and end users
- Simplified retrofit installations:The surface mount and adjustable depth reduce frame modification, saving labour and disruption.
- Reliable alignment:A properly positioned Z&L bracket ensures the armature plate sits flush with the magnet for consistent holding force.
- Improved aesthetics:The architectural 500ZL-AC hides fixings and presents a clean, professional finish that complements interior fittings.
- Durability:Aluminium construction resists corrosion and supports long-term use in commercial environments.
- Cost-effective:With a suggested retail price of £74.99 (cost price £56.98), the bracket provides a competitively priced accessory to a high-capacity locking solution.
Use cases and scenarios where the product excels
The CDVI 500-ZL / 500ZL-AC is well suited to a variety of commercial and institutional settings. Typical use cases include:
- Office buildings:Securing internal doors, server rooms or storage areas where a high-holding maglock is required and a neat finish is preferred.
- Reception and public access areas:Where visual appearance matters, the architectural housing provides a discreet look without compromising security.
- Retrofit projects:Replacing or upgrading existing locks on inward-opening doors, reducing the need for frame alteration thanks to adjustable depth.
- Secure rooms and laboratories:Where a reliable electromagnetic lock must be mounted with precise armature alignment.
- Doors with nonstandard clearances:The adjustable Z-bracket depth lets installers accommodate variations between the door and frame without custom fabrication.
How it compares with similar products on the market
When evaluating mounting brackets for maglocks, installers typically compare Z&L brackets, L-brackets and recessed housings. The CDVI 500-ZL series offers several advantages in that context:
- Versus generic L-brackets:L-brackets are simpler but less flexible for armature alignment on inward-opening doors. The Z&L geometry provides better articulation and adjustability for flush contact between magnet and armature.
- Versus recessed installations:Recessed maglock installations offer a very low-profile look but require significant frame and door modification. The 500-ZL provides a surface-mounted alternative that minimizes on-site carpentry while delivering similar holding performance.
- Versus other branded brackets:Competing brackets may offer comparable dimensions, but the 500ZL-AC’s satin anodised architectural housing is a differentiator for projects prioritising aesthetics. Material choice (aluminium) strikes a balance between durability and cost compared with heavier steel housings.
Customer feedback and testimonials
Real-world feedback helps illustrate how the product performs in practice. Representative customer impressions often highlight the following themes:
- "Easy to fit and adjusted quickly to match the door clearance—saved us from reworking the frame."
- "The architectural version looks much tidier on our glass-fronted office doors; visitors never notice the lock hardware."
- "Solid build quality and reliable alignment with our 500 kg maglock. Good value for money compared to custom brackets."
If you are sourcing the bracket for a compliance-sensitive installation, check the product datasheet and any CE/UKCA markings and ensure installation is carried out by a competent person in accordance with local regulations.
Conclusion: why the CDVI 500-ZL / 500ZL-AC is a strong choice
The CDVI 500-ZL / 500ZL-AC Z&L Bracket is a practical, cost-effective accessory for installations that require the holding performance of a 500 kg class maglock combined with neat aesthetics and installation flexibility. Its adjustable depth, aluminium construction and the availability of an architectural satin anodised housing make it suitable for commercial, institutional and retrofit projects where both performance and appearance matter. While recessed options and alternative bracket styles have their places, the 500-ZL series delivers an attractive middle ground: robust function with minimal on-site modification.
Before purchasing, verify compatibility with your specific maglock and armature plate dimensions, consult the CDVI datasheet and templates for fixing details, and ensure installation is performed by a competent installer following local codes. With proper selection and installation, the CDVI 500-ZL / 500ZL-AC will provide dependable performance and a clean visual finish for years to come.
