Introduction to the RGL BK600ZL and its key features
The RGL BK600ZL is an adjustable Z & L bracket set designed specifically for use with RGL's ML600 slimline magnetic locks (including ML600, ML600-M and ML600-D). Built from anodised aluminium and supplied with the necessary mounting fixings, the BK600ZL gives installers the flexibility to mount maglocks on inward-opening doors while allowing precise alignment of the magnet and armature plate. With roughly 18 mm of adjustment, corrosion-resistant finish and a compact, light design, the BK600ZL is positioned as a practical accessory for professional installers and competent DIY users alike.
Detailed specifications and the benefits they deliver
Understanding the BK600ZL begins with the specifics. Below are the key product details and how they translate into real-world benefits.
- Product code: BK600ZL — easy to order and reference on datasheets.
- Package contents: Z & L bracket set with mounting fixings — hardware included for straightforward installation.
- Suggested price: 17.99 (indicative retail price) — a cost-effective addition to an ML600 maglock installation.
- Z bracket dimensions: 2 7 180 L 50 W 50 H mm
- L bracket dimensions: 250 L 29 W 47 H mm
- Weight (unboxed): 556 g;Weight (boxed): 644 g
- Material & finish: Aluminium with an anodised finish for corrosion resistance and a neat appearance.
- Maximum adjustment: Approx. 18 mm — allows fine alignment between magnet and armature plate.
These specifications combine to deliver practical benefits:
- Fine alignment— the ~18 mm adjustment range helps installers achieve optimal face-to-face contact between the magnet and armature plate for maximum holding force and reliable operation.
- Corrosion resistance and looks— anodised aluminium resists rust, is suitable for many indoor environments, and offers a professional finish that complements modern doors and frames.
- Supplied fixings— saves time sourcing mounting hardware and helps ensure installers have the correct fasteners for the brackets.
- Lightweight but strong— aluminium keeps weight down without compromising structural support for the ML600 maglock class (600 lb / ~280 kg).
Use cases and scenarios where the BK600ZL excels
The BK600ZL is particularly useful in installations where door configurations or construction prevent a simple surface-mount of the maglock. Typical situations include:
Many commercial and residential inward-opening doors require an L or Z bracket arrangement so the magnet can be mounted to the frame while the armature plate is secured to the door leaf. The BK600ZL is purpose-built for this arrangement and provides the adjustment needed to align the lock for secure operation.
Where frames are recessed, have decorative trims, or the magnet cannot sit flush with the armature, the BK600ZL's adjustable offsets allow installers to position the magnet exactly where it needs to be without resorting to improvised shims or custom fabrication.
When upgrading legacy doors to maglock access control systems, installers frequently encounter non-standard dimensions or wear in the frame. Adjustable brackets like the BK600ZL reduce installation time by compensating for irregularities and enabling the ML600 range to be used in a wider variety of door types.
For higher security doors that use double maglocks, two BK600ZL sets ensure consistent alignment across both locks and simplify matching the armature plates. The fact the brackets are supplied with fixings further streamlines these multi-lock installations.
Comparisons with similar products on the market
When choosing a mounting bracket for a maglock, installers typically compare adjustable aluminium sets like the BK600ZL with several alternatives. Below is a concise comparison highlighting where the BK600ZL stands out.
Fixed brackets are often cheaper but lack the adjustment range. They require precise measurement and sometimes on-site modification. The BK600ZL is more flexible during installation and reduces the need for rework or custom fitting.
Heavy steel brackets offer ruggedness and are favoured for extremely exposed or high-impact installations. However, they are heavier, more noticeable aesthetically, and often require corrosion-resistant coatings. The BK600ZL, being anodised aluminium, balances strength with a cleaner, lighter aesthetic suitable for most indoor commercial applications.
Some maglock manufacturers sell integrated mounting kits tailored to their locks. These can offer perfect compatibility but may be more expensive or only available with specific lock models. The BK600ZL is specifically engineered for the RGL ML600 family, delivering a near plug-and-play option at a competitive price point.
Lower-cost plastic brackets exist for very light-duty use but are not appropriate for high-holding-force maglocks like the ML600. Aluminium brackets such as the BK600ZL provide a superior combination of durability and stability, ensuring the full rated holding capacity of the maglock is realised.
Customer feedback and typical reviews
There are no formal, named customer reviews provided here, but installers and contractors who choose adjustable anodised aluminium brackets commonly report the following types of feedback:
- "Quick to fit and adjust"— installers appreciate the included fixings and the smooth adjustment mechanism, reducing time on site.
- "Neat finish"— the anodised surface looks professional and resists tarnishing in office and retail environments.
- "Good value for purpose"— priced competitively against fixed or steel alternatives, customers find the BK600ZL offers a practical balance of price and function.
- "Useful for retrofit jobs"— when older frames or non-standard doors are encountered, the adjustable range avoids complex custom work.
These representative comments reflect the typical strengths buyers look for in a bracket: ease of installation, finish quality and adaptability. As with any accessory used in security or fire-rated installations, buyers should confirm compatibility and certification for their specific door/maglock combination.
Installation notes and compliance considerations
The BK600ZL is supplied with mounting fixings and designed to pair with the RGL ML600 range. A few practical notes for installers:
- Two BK600ZL brackets are commonly used for double maglock configurations to ensure symmetrical alignment.
- Always refer to the ML600 datasheet for fire-test references and validated combinations if fitting to a fire-rated door set (BS EN 1634-1:2014 references are available on the ML600 datasheet).
- Follow the manufacturers installation instructions and local building regulations when working on life-safety, egress, or fire-door systems.
Conclusion: Why the BK600ZL is a great choice
The RGL BK600ZL adjustable Z & L bracket set offers a pragmatic, cost-effective solution for mounting ML600 series maglocks on inward-opening doors and other challenging frame configurations. Its anodised aluminium construction combines corrosion resistance and a tidy appearance with the light weight and mechanical reliability installers need. The approximately 18 mm of adjustment gives sufficient latitude to achieve perfect magnet-to-armature alignment without resorting to heavy modification or bespoke fabrication.
For contractors, security installers and competent DIY users seeking a reliable bracket specifically matched to the RGL ML600 maglock family, the BK600ZL is a well-considered choice. It reduces installation time through included fixings, supports retrofit and upgrade projects, and provides the practical adjustment range required for consistent locking performance. Where fire-door compliance is necessary, the BK600ZL forms part of validated combinations when used with the correct ML600 configurations — but always check the ML600 datasheet and local standards before final installation.
In short, the BK600ZL strikes the right balance between functionality, finish and value, making it a smart accessory to have on the van for any maglock installation that demands adaptability and a professional result.
