Detailed Specifications and Benefits
The technical design of the 300‑ZL kit focuses on giving installers maximum flexibility while ensuring a robust, compliant installation when used with compatible maglocks. Key specification highlights include:
- Mounting:Surface mounting with dedicated Z and L plates to support typical inward and outward opening door configurations.
- Dimensions:Z bracket 175 × 50 × 50.5–101 mm (H × W × depth, adjustable); L bracket 248 × 50 × 30 mm (H × W × D).
- Material / Finish:Satin‑anodised aluminium provides corrosion resistance, a professional finish and straightforward site handling.
- Operating environment:Rated for −20°C to +60°C operation, suitable for most internal commercial environments.
- Weight:0.77–0.84 kg depending on regional variant/listing.
- Certifications:EN 1634‑2 referenced — installers should confirm CE/UKCA compliance with suppliers and adhere to local approvals for fire-door and escape-route use.
Benefits that directly follow from these specifications include:
- Versatility:The inclusion of both Z and L brackets means the same kit can be used across multiple door/frame types, reducing the need for multiple part numbers on a job.
- Time savings:Adjustable Z bracket depth speeds up alignment and reduces on-site modifications.
- Aesthetics and durability:Satin‑anodised finish not only looks professional but also withstands the wear of a busy environment.
- Predictable performance:Designed specifically for 300 kg and 400 kg maglocks, delivering the mounting integrity needed for the lock’s rated holding capacity when installed per manufacturer guidance.
Use Cases and Scenarios Where the 300‑ZL Excels
The 300‑ZL kit is aimed at commercial and institutional installations where surface-mounted electromagnetic locks are the preferred solution. Typical scenarios include:
Older door frames often lack the neat recesses or standardized connections required for concealed maglock fittings. The 300‑ZL’s surface-mount approach and adjustable Z bracket let installers adapt to uneven jambs, thicker frames or odd armature offsets without custom fabrication.
In fit-outs where multiple doors require maglocks (offices, warehouses, health-care wings), stocking a single Z+L kit that covers both inward and outward opening doors simplifies logistics and reduces the number of different components on-site.
Facilities teams replacing or upgrading locks benefit from the 300‑ZL because it’s a drop-in style kit that reduces installation time and disturbances. The satin finish matches many interior hardware aesthetics used in public and corporate spaces.
Where a maglock must be mounted in a less common position (for example, offset armature fixation) the adjustable Z bracket depth options allow precise alignment — critical for ensuring full face contact between armature plate and magnet for maximum holding force.
Comparisons with Similar Products
The market offers a range of maglock bracket kits. Comparing the 300‑ZL against common alternatives helps clarify when it’s the right choice:
- Dedicated single-bracket solutions:Some kits provide only an L or a Z plate. While these can be fine for standard installations, they lack flexibility. The 300‑ZL’s inclusion of both L and Z options removes guesswork and reduces the risk of needing additional parts.
- Universal or adjustable multi-purpose brackets:Universal brackets attempt to cover many lock sizes and ratings. The 300‑ZL focuses specifically on 300 kg and 400 kg maglocks, matching bracket dimensions and fixings to those loads — this dedicated fit reduces installation compromise and aligns with manufacturer guidance.
- Heavy-duty welded or fabricated brackets:These are often over-specified and more costly for standard internal maglock jobs. The 300‑ZL balances robust performance with a cost-effective satin‑anodised aluminium construction tailored to the rated maglocks.
In short, the 300‑ZL sits between single-purpose, limited kits and very heavy-duty custom brackets — offering the right mix of compatibility, adjustability and finish for standard commercial maglock installs.
Installation Notes and Compliance Considerations
While the kit is designed for straightforward surface mounting, installers should follow certain best practices:
- Always isolate power and follow lock manufacturer safety guidance before beginning installation.
- Confirm local approvals (CE/UKCA) and fire-door compliance with the supplier. EN 1634‑2 is referenced; however, regional certification and correct use on escape routes must be verified.
- For fire doors or escape-route doors, consider professional installation by a qualified installer to ensure continued door certification and correct operation.
Customer Testimonials and Reviews
While formal customer testimonials for this specific kit may vary by supplier and region, typical installer feedback for kits of this type and from CDVI tends to focus on a few recurring points:
- Installation speed:Installers frequently note that having both Z and L brackets in one kit avoids return visits for missing parts.
- Fit and finish:The satin‑anodised aluminium finish is commonly praised for its professional look and ease of handling.
- Reliability:When used with compatible maglocks and installed per datasheet guidance, users report consistent performance and solid armature engagement.
If you require verified case studies or named customer reviews, check with your supplier or regional distributor for installation reports or references specific to your industry sector.
Pricing and Value
The suggested retail price for the 300‑ZL Z & L Bracket Kit is listed at 29.99 (local currency applies). With a cost price of 21.28, the kit represents an affordable component in access control projects when balanced against the time savings, reduced part variety and improved installation reliability it delivers.
Conclusion: Why Choose the 300‑ZL Z & L Bracket Kit?
For contractors, security installers and facilities teams working with 300 kg and 400 kg maglocks, the 300‑ZL Z & L Bracket Kit is a practical, well-specified solution. Its combination of both Z and L brackets, adjustable Z depth, satin‑anodised finish and clear dimensional data make it a versatile kit for a wide range of commercial internal door scenarios. The kit reduces on-site uncertainty, speeds installation and delivers a professional finish — all at a cost-effective price point.
Before installation, always consult the manufacturer datasheet (https://cdn.dynamictech.uk/connectec/uploads/datasheets/679ccfc46c761_300zldatasheet.pdf) for full dimensions and compatibility, and confirm local compliance for use on fire or escape-route doors. With correct selection and installation, the 300‑ZL kit is a dependable choice for consistent maglock mounting and long-term performance.
