Heavy Duty Electric Door Strike Lock 12V DC - Adjustable

In this review we look at a heavy duty electric door strike designed to convert cylindrical locksets into an electronic access control point. The single biggest reason to consider this model is its combination of high jaw strength and field-selectable operation: installers get a 2,200-lb jaw rated strike that can be set to fail-safe or fail-secure in the field, making it a versatile choice for commercial and residential retrofit projects where strength and flexibility matter.

Key Features

• Field-selectable operation: The unit can be changed between fail-safe and fail-secure modes on site, giving installers flexibility for different security requirements.
• High impact strength: With a maximum jaw strength of 2,200-lb (1000kg) this strike handles heavy use and resists forced entry better than standard strikes.
• Long life cycle: The mechanism is tested to 500,000 cycles, which means dependable service in busy doorways without frequent replacement.
• Complete accessories included: The package includes mounting hardware and screw terminals to simplify installation and wiring.
• Cylindrical lock compatibility: It is designed specifically to convert cylindrical locksets into an access-controlled lock, making retrofits straightforward.

Who It's For

This electric door strike is best for contractors, facility managers, and DIY-savvy homeowners who need a robust, versatile strike for retrofitting existing cylindrical locksets into an access control system. Its high jaw strength and long cycle rating make it well suited for commercial entrances, multi-family buildings, or high-traffic exterior doors where durability matters.

Those who should look elsewhere include buyers who need integrated smart-lock features or battery operation; this is a hardwired 12V DC unit intended for conventional access control setups. Also check door frame dimensions carefully before ordering to ensure compatibility with your frame and locking hardware.
