ABH Armature Base Only 20040-628 | Aluminum Finish

The ABH 20040-628 is a high-durability armature base only, specifically engineered to serve as a foundational component for electromagnetic door holders. Finished in architectural Satin Aluminum (628), this heavy-duty base provides the structural support necessary to house the steel contact plate that keeps fire and smoke doors securely held open. As a versatile solution for door restoration, the 20040-628 allows facility managers to replace a damaged or worn base without the expense of purchasing a complete new assembly.

Universal Structural Support

The ABH 20040-628 is designed with cross-compatibility in mind, making it a "go-to" repair part for institutional maintenance:

• Manufacturer Versatility: This base is uniquely designed to be used on magnetic releases from most major manufacturers. This makes it a cost-effective solution for commercial door security when hardware from different brands is installed throughout a facility.
  
• Refined Aluminum Finish: The 628 finish provides a clean, professional appearance that matches standard commercial aluminum storefronts and interior office hardware.
• Component-Level Repair: By offering the base only, ABH allows technicians to perform a surgical solution for door surface repair, replacing only the part that has been subjected to physical impact or wear.

Optimized for High-Traffic Fire Openings

In commercial corridors and stairwells, electromagnetic holders are under constant tension. The ABH 20040-628 ensures that the critical link between the door and the wall remains rigid:

• Rugged Construction: Built to withstand the daily stress of manual door releases and the high-torque environment of industrial fire doors.
• Flexible Maintenance: Since this unit is the base only (no mounting screws), it is the ideal choice for technicians who already have specialized fasteners or are remounting a unit to an existing location.
• Code Compliance Support: A stable base is essential for ensuring the armature plate remains flush with the magnet; a loose or cracked base can lead to failure during fire inspections.
