HES 10530602 Hes 4500C-12/24-605 Electric Strike
When you need to retrofit an electric strike into metal frames without field modifications, the HES 4500C series solves the pre-cut coordination problem. This dual-voltage strike fits ANSI 4-7/8" x 1-1/4" frame preps with center-to-center spacing matching most legacy hardware installations. The field-selectable 12/24V DC operation eliminates voltage-specific inventory while the fail-secure design maintains physical security during power interruptions—critical for perimeter doors and sensitive access zones.
Key Features
- Fits standard ANSI 4-7/8" x 1-1/4" frame cutouts without field modification or welding
- Field-selectable 12/24V DC operation simplifies inventory and reduces installation planning
- Fail-secure configuration maintains locked position during power loss or system failure
- Satin brass (605) finish matches architectural hardware in commercial and institutional settings
- Accepts both cylindrical and mortise locksets with standard latchbolt profiles
- Center-hung keeper design accommodates typical frame misalignment without adjustment
- Continuous duty rating supports high-traffic applications without thermal cycling concerns
- Single-gang trim plate provides clean finished appearance in exposed installations
The 4500C series addresses the retrofit challenge where existing frame preps can't accommodate larger strikes or complex cutout patterns. The center-hung keeper self-aligns with minor frame tolerances, reducing field adjustment time during commissioning. Field voltage selection means you can stock one SKU for multi-building campuses with mixed power infrastructure—just set the jumper during installation based on the local access control panel output.
This strike works in applications where maintaining security posture during network or power events is non-negotiable: server rooms, pharmacy access, evidence storage, and exterior doors on unmonitored elevations. The fail-secure mode ensures the door remains locked until deliberately released through authorized credentials. Pair with electromagnetic locks on egress paths and use these strikes on entry-only doors where code allows keyed egress. The satin brass finish integrates with traditional commercial lever sets and panic hardware without creating visual inconsistencies across the building envelope.
