Hikvision DS-K4H250-LZ LZ-Bracket of Magnetic Lock for DS-K4H250S/D - Designed for Secure, Reliable Magnetic Lock Installations on Inward-Opening Doors with Maximum Durability and Compatibility

The Hikvision DS-K4H250-LZ is a professional-grade LZ bracket designed specifically to facilitate the installation of Hikvision's DS-K4H250S and DS-K4H250D magnetic locks onto inward-opening doors. In any access control setup, the correct mounting accessory is just as critical as the locking hardware itself. Without the right bracket, the effectiveness and holding force of the magnetic lock may be compromised—especially on doors where a conventional surface mount is either impossible or structurally unsound.

This LZ bracket set provides the proper mounting orientation by combining both an “L” and a “Z” bracket to adapt the magnetic lock and armature plate to the inward-swinging configuration of the door. It creates the necessary physical space and structural support to ensure that the lock holds with maximum force and reliability under everyday use, even in high-traffic or sensitive security environments.

Crafted from high-strength aluminum alloy and treated with an anodized finish for corrosion resistance, this bracket is engineered not only for strength but for long-term performance and aesthetics. The bracket is ideal for use in schools, hospitals, banks, retail stores, government facilities, and any installation that demands secure, precise mounting of magnetic locks on inward-opening doors—where reliable electromagnetic force and mounting precision are non-negotiable.

Features

• LZ Configuration for Inward-Swinging Door Compatibility
  The Hikvision DS-K4H250-LZ bracket provides a secure and professional method of installing magnetic locks on inward-opening doors—doors that are notoriously more difficult to equip with surface-mounted locking solutions. The LZ design offers a stable, reinforced mounting surface for both the magnet and the armature plate, aligning them perfectly and allowing the lock to function with its full rated strength.

• Compatible with Hikvision’s Most Popular Magnetic Locks
  Purpose-built for the DS-K4H250 series—including both the single-door DS-K4H250S and the double-door DS-K4H250D magnetic locks—this bracket ensures a precise fit. This eliminates guesswork and prevents misalignment, allowing for faster, safer, and more accurate installations, which is critical in time-sensitive or large-scale deployment environments.

• High-Durability Aluminum Construction
  Manufactured using premium aluminum alloy, the DS-K4H250-LZ provides exceptional strength without excessive weight. The material is treated for durability and corrosion resistance, making it suitable for long-term use in both indoor and sheltered outdoor installations where longevity and stability are key factors.

• Streamlined, Installer-Friendly Design
  With pre-drilled holes, cutout notches, and optimized spacing, this bracket system is engineered to make installation as fast and straightforward as possible. Whether you're an integrator managing dozens of units or a technician performing a one-time upgrade, the DS-K4H250-LZ drastically reduces complexity during setup.

• Professional Finish for Seamless Aesthetic Integration
  Featuring a sleek, clean, anodized finish, this bracket does not interfere with the visual appeal of the entry point. This is especially important for offices, retail spaces, or hospitality environments where both security and appearance matter equally.

• Banking and Financial Institutions
  Ensure the highest security for cash handling rooms, manager’s offices, or server areas by securely mounting magnetic locks using the DS-K4H250-LZ bracket to preserve the full holding force and operational integrity.

• Educational Institutions
  Prevent unauthorized access to classrooms, staff lounges, and IT facilities by enabling precision-mounted magnetic locks that are tamper-resistant and cleanly installed even on challenging door frames.

• Retail Stores and Chain Supermarkets
  Secure stockrooms, break rooms, and restricted areas without compromising door design or requiring major structural modifications, using this LZ bracket to enable full lock functionality.

• Government Buildings
  Maintain tight control over high-security areas in public institutions with lock installations that meet regulatory and operational expectations.

Why You Should Choose This System

The Hikvision DS-K4H250-LZ bracket is more than just an accessory—it's the structural backbone that enables Hikvision magnetic locks to perform to their full potential in inward-opening door configurations. Many buyers and installers overlook the importance of compatible mounting hardware until they encounter limitations with door structure or swinging direction. Choosing the DS-K4H250-LZ from the start prevents installation delays, misalignment issues, and performance degradation of the lock mechanism.

By choosing this bracket, you eliminate risks associated with improvised or generic mounting solutions, ensuring that your DS-K4H250S or DS-K4H250D magnetic lock retains full magnetic hold and mechanical strength, exactly as designed. The bracket’s purpose-built design minimizes vibration, enhances alignment, and ensures maximum surface contact between the lock and the door. It gives you the confidence that the lock will hold firm under repeated use, heavy traffic, and even minor impacts.

FAQ

Is this bracket necessary for all DS-K4H250 installations?
Only for inward-opening doors. For outward-swinging doors, other mounting options may be used. The LZ bracket is essential when traditional mounting isn't structurally supported.

Can I use this bracket for outdoor doors?
Yes, but only in covered outdoor locations. For fully exposed exterior doors, additional weather shielding is recommended to protect both the lock and bracket.

Does this bracket affect the strength of the magnetic lock?
No. In fact, it preserves and properly channels the full magnetic force by ensuring correct alignment and contact between the armature plate and the magnet.

Does it come with screws or do I need to buy hardware separately?
The DS-K4H250-LZ includes standard mounting screws and installation components designed specifically for use with the DS-K4H250 series.

Can this be used with third-party magnetic locks?
While it may fit other models, it’s designed and tested exclusively for Hikvision DS-K4H250S and DS-K4H250D locks. Mwanga recommends only using this bracket with its intended Hikvision locks to ensure proper function.
