ABH Complete Armature Assembly 20020-628 | Aluminum Finish

The ABH 20020-628 is a professional-grade complete armature assembly designed for high-performance electromagnetic door holders. As a vital solution for door restoration, this assembly ensures your fire and smoke doors remain securely held and properly released during an emergency. Finished in durable Aluminum (628), this unit combines architectural aesthetics with the heavy-duty structural integrity required for commercial and institutional life-safety systems.

Universal Compatibility and Versatile Application

One of the most valuable features of the ABH 20020-628 is its cross-brand versatility. While engineered to the highest standards, this assembly is designed as a universal solution for commercial door security:

• Multi-Manufacturer Use: This armature can be utilized as a direct replacement on magnetic releases from various manufacturers, making it an essential stocked item for facility maintenance teams.
  
• Complete Base Assembly: Unlike partial kits, this includes the full base and the specialized steel plate, ensuring a flat, magnetic surface area for maximum holding force.
  
• All-Inclusive Hardware: Comes standard with precision mounting screws, allowing for an immediate "out of the box" installation or repair.
  

Engineered for Life-Safety Compliance

The relationship between a magnetic door holder and its armature is critical for NFPA and fire code compliance. The ABH 20020-628 provides a reliable contact point that:

• Prevents Door Sag Issues: By providing a secure, adjustable anchor point, it acts as a permanent solution for door surface repair when old, pitted, or misaligned armature plates fail to hold.
• Self-Aligning Design: The assembly allows for the slight pivoting necessary to maintain flush contact with the magnet, even if the door or wall is slightly out of plumb.
• Corrosion Resistance: The 628 Aluminum finish provides a clean look that resists oxidation in high-traffic hallways and stairwells.
