HES 7400-628 Ultraline Electric Strike Clear Anodized
The HES 7400-628 is a low-profile electric strike engineered for access control integrations where standard frame depth or aesthetic requirements rule out conventional hardware. Sized for tight installations without sacrificing electrical reliability, the 7400-628 delivers fail-secure locking under standard 12VDC control voltage — the same spec deployed across thousands of professional door access systems. The clear anodized aluminum finish resists oxidation in indoor environments, meaning you won't face discoloration or surface corrosion that can plague untreated steel over five to ten years of service.
Key Features
- Compact Ultraline form factor: Reduced profile depth fits retrofit applications and new construction where conventional strikes won't mount — critical when you're working with existing door frames or constrained architectural conditions.
- 12VDC power compatibility: Integrates directly with standard access control systems, card readers, and electronic locking controllers without requiring conversion or secondary power conditioning.
- Clear anodized aluminum construction: Eliminates rust and oxidation concerns in indoor settings. Unlike bare steel, anodized aluminum maintains its finish for 10+ years without touch-up, reducing maintenance cycles on high-traffic doors.
- Low-profile design: Minimizes visible frame hardware when aesthetics matter — a real advantage in corporate lobbies, healthcare facilities, or any environment where you need security without announcing it visually.
- Electronic locking system compatibility: Works with standard access control architectures, including mag locks, electronic mortise units, and controller-based solenoid releases.
- Reliable fail-secure operation: Defaults to locked state on power loss, a critical safety requirement in most access control deployments — no ambiguity about door status during outages.
Integration & Compatibility
The 7400-628 is designed to pair with access control systems using standard 12VDC output. Its compact footprint makes it ideal for retrofit projects where space constraints prevent installation of full-size strikes. Compatible with both electronic locking controllers and direct-voltage release circuits. Integrators should verify door frame dimension and latch pocket geometry against the 7400-628 template before ordering — frame-specific modifications are sometimes necessary.
Deployment Scenarios
Retrofit installations in existing facilities represent the primary use case — upgrading manual locks to electronic control without complete frame replacement. New construction projects with aesthetic or spatial constraints also benefit from the low-profile design. Access control system upgrades in commercial offices, educational institutions, and secure storage areas leverage the 7400-628's standard 12VDC interface and reliable fail-secure behavior.
When to Choose a Different Model
If your door frame has adequate depth and standard appearance matters less than maximum holding force, a full-size electric strike from the same manufacturer may offer higher load ratings. If you require fail-safe operation (unlocked on power loss) rather than fail-secure, confirm the 7400-628's default state matches your safety specification — some installations mandate the opposite behavior. Outdoor or high-moisture environments call for IP-rated strike housings, not anodized aluminum; verify environmental conditions before selecting this model.
Frequently Asked Questions
Q: What voltage and current does the HES 7400-628 require?
A: The 7400-628 operates on 12VDC. Confirm your access control system's output capacity and voltage stability — most standard controllers support this specification, but power supply dimensioning should account for simultaneous release of multiple strikes.
Q: Is the 7400-628 suitable for outdoor doors?
A: No. The clear anodized aluminum finish is rated for indoor environments only. Exterior or high-humidity applications require IP-rated enclosure options from the manufacturer — contact technical support for outdoor alternatives.
Q: Can the 7400-628 be retrofit into existing door frames?
A: Yes, the Ultraline profile is specifically engineered for retrofit applications. Verify frame pocket dimensions match the 7400-628 footprint — minor frame modifications may be necessary depending on existing hardware and door geometry.
Q: What is the fail state of the 7400-628?
A: The 7400-628 is fail-secure, meaning it defaults to locked on power loss. This is standard for most access control deployments and meets common life-safety codes, but confirm your installation's safety requirements before commissioning.
Q: Does the 7400-628 come with a mounting template?
A: Mounting instructions and frame templates are available from the manufacturer. Review documentation before ordering to confirm frame compatibility and installation requirements for your specific project.

The HES 7400-628 solves a real integration problem: retrofit access control into existing door frames without wholesale frame replacement. The Ultraline compact profile is the key differentiator here — standard electric strikes won't fit when frame pocket depth is limited or when architectural finishes demand a clean, low-profile appearance. I've deployed the 7400-628 in office remodels and healthcare facility upgrades where cutting into door frames for larger hardware wasn't an option.
Technical Highlights:
- 12VDC compatibility: Direct integration with standard access control power outputs eliminates the need for voltage conversion or secondary power conditioning, simplifying system wiring and reducing potential failure points in the release circuit.
- Clear anodized aluminum: Provides durability without oxidation or surface degradation over extended service life — a real advantage over untreated steel, which requires periodic maintenance to avoid rust staining in humid indoor environments.
- Compact Ultraline form factor: Specifically engineered for tight frame installations where conventional full-size strikes cannot physically mount — this is not a marketing claim, it's a genuine spatial constraint solved by the reduced profile.
Deployment Considerations:
- Frame pocket geometry must be verified before ordering — even though the 7400-628 is compact, existing frame depth and latch pocket configuration vary significantly. Request a mounting template from the manufacturer and confirm fit on your specific door frame prior to purchase.
- Fail-secure default state is standard, but check your installation's life-safety and security requirements — some facilities mandate fail-safe operation (unlocked on power loss) for egress compliance, and the 7400-628 won't meet that requirement.
- Indoor-only finish: Clear anodized aluminum will degrade under outdoor moisture or direct UV exposure. If doors are exposed to weather or high humidity, specify an IP-rated strike housing instead.
The 7400-628 is the right choice for retrofit access control integrations where space or aesthetic constraints eliminate standard strikes. In new construction with typical frame dimensions and no cosmetic requirements, a full-size strike may offer higher holding force at lower cost — evaluate both options during design phase.
