Seco-Larm SD-996C-NUVQ Electric Door Strike
The Seco-Larm SD-996C-NUVQ offers vertical adjustment and a sliding shim keeper, plus a deadlatch ramp to fit a wide range of locks. It ships with five stainless-steel ANSI faceplates and a trim plate to hide gaps during installation. It supports both fail-safe and fail-secure configurations, making it adaptable for doors that require either power-off open or locked states. Best for facilities needing adjustable fit with cosmetic concealment during retrofit. Potential limitation: ensure compatibility with your door’s lockset and latch alignment before purchase.
Heavy Duty Electric Door Strike Lock (Pulaim)
The Pulaim electric strike lock is described with two operation modes, allowing either fail-safe or fail-secure configurations. It emphasizes a robust aluminum construction and high impact resistance, suitable for heavy-use doors. The product notes highlight installation considerations (door strike size and power supply adequacy) and suggest possible coil-related issues may relate to power availability rather than the strike itself. Choose this for heavy-duty applications where conversion between modes is beneficial, but verify power supply capacity for long-term reliability.
UHPPOTE ANSI Electric Door Strike Lock
UHPPOTE’s ANSI electric strike emphasizes fail-secure operation and a solid electroplated metal shell to resist rust and abrasion. Its design suits warehouses or confidential rooms needing door security during power outages. It’s compatible with mortise or cylindrical locks and supports up to 3/4″ latchbolt projection. Best for environments prioritizing ongoing security when power is unavailable, though installation should confirm latch compatibility with existing hardware.
HES 1500C Complete Pac
The HES 1500C Complete Pac is designed to work with cylindrical or mortise locks and includes multiple faceplates (1J, 1K, 1KD, 1KM) to cover various latchbolt configurations. Its dual-voltage capability (12/24 VDC) supports a broad range of access control systems. This modular approach factors into installation planning, making it a strong choice when switching between lock types. A limitation to note: ensure your lockset is compatible with the included faceplates and mounting geometry for reliable operation.
2026 Upgraded ANSI Electric Strike (YJMKOI)
The 2026 Upgraded ANSI Strike from YJMKOI highlights a high-quality alloy body with corrosion resistance and a stated 1000 kg (2200 lbs) impact resistance after electrification. It supports both fail-safe and fail-secure modes and claims long service life over 500,000 cycles. Best for demanding facilities seeking durable performance and flexible operation modes, especially where future upgrades or changes in door control schemes are anticipated. Note the description emphasizes a wide application range rather than specific lock compatibility details.
HES 4500C Electric Strike Complete Pac
The HES 4500C Complete Pac supports cylindrical or mortise locksets with up to a 3/4″ latchbolt throw and includes two faceplates to accommodate both lock types. It’s noted as a low-profile, heavy-duty, fire-rated solution. Relocation of strike prep may be required for certain lock series (e.g., Schlage L Series, Yale 8700). This makes it a strong choice for multi-lock projects, but installation planning should verify compatibility with existing strike prep or door prep.
QWORK Electric Door Strike Lock (2 Pack)
QWORK’s two-pack electric strike lock features a durable stainless steel panel and zinc alloy body. It offers two modes—fail-safe and fail-secure—via a simple screw adjustment. With a maximum impact strength around 882 lbs (400 kg), it’s suitable for dual-door setups or cost-conscious installations requiring straightforward operation. Choose this for basic, reliable two-door applications or as a budget-friendly testing option, but confirm latch compatibility with your door hardware.
Buying Guide
What to consider when selecting an electric strike mortise lock:
- Door compatibility: Determine whether your door uses cylindrical or mortise locks and verify latchbolt projection compatibility with the strike’s faceplates and mounting.
- Fail-safe vs. fail-secure: Decide whether you need the door to open on power loss (fail-safe) or stay locked (fail-secure). Some installations require a specific mode due to exit routes or safety regulations.
- Material and finish: Look for corrosion-resistant alloys or stainless steel for durability in high-traffic or outdoor environments.
- Faceplates and adjustments: Consider models with interchangeable faceplates or adjustable strike alignment to simplify retrofit on existing doors.
- Electrical requirements: Check voltage (12V vs. 24V) and power supply needs. Ensure your controller or access control system can support the chosen strike’s current draw.
- Installation notes: Some strikes require relocation of strike prep or may have compatibility caveats with specific lock brands. Plan for potential modification during retrofit.
- Reliability and cycles: For high-traffic areas, prioritize components with high cycle ratings and proven mechanical endurance to minimize maintenance.
FAQ
- What is an electric strike mortise lock?
An electric strike mortise lock uses an electric mechanism to control the release of a door latch, allowing access control integration with doors using mortise or cylindrical locksets.
- What does fail-safe mean for door strikes?
Fail-safe means the door unlocks or opens when power is lost, ensuring safe egress.
- What does fail-secure mean for door strikes?
Fail-secure keeps the door locked when power is lost, improving security during outages.
- Do I need special power supplies for these strikes?
Yes. Most strikes use 12V or 24V DC; verify your access controller’s output and ensure the supply can handle the strike’s current draw.
- Can these strikes work with existing locks?
Many models are designed to retrofit either cylindrical or mortise locksets, but always confirm latch compatibility and mounting geometry with your door hardware.
- Is maintenance required for electric strikes?
Regular checks for corrosion, misalignment, and dirt buildup help maintain reliability, especially in high-traffic or outdoor environments.
