Heavy Duty Electric Door Strike Lock - ANSI Fail-Secure/Fail-Safe

In this review of the Heavy Duty Electric Door Strike Lock the bottom line is simple: this is a solid option for installers and facility managers who need a rugged, metal electric strike that adapts to either fail-safe or fail-secure operation. The reviewer found it best for retrofitting cylindrical or mortise locksets into an access control system because of its heavy alloy construction and high impact rating. The main reason to consider it is the combination of adjustable operation mode and long mechanical life, though buyers should confirm frame dimensions before ordering.

Key Features

• Dual Mode Operation: Easily switches between fail-safe and fail-secure by loosening and retightening a screw so you can match your access control policy without replacing parts.
• High Impact Resistance: Rated to resist up to 2200 lb of impact when powered, providing solid physical security for commercial doors.
• Durable Construction: Made from high-quality alloy metal, the strike is built to withstand repeated cycles and industrial use.
• Long Mechanical Life: Specified for roughly 300,000 operations, making it suitable for moderate- to high-traffic openings.
• Versatile Installation: Designed to work with cylindrical and mortise locksets to convert a standard latch into an electronically controlled lock.

Who It's For

This electric strike is targeted at small business owners, maintenance teams, and independent installers who need a heavy duty strike for commercial doors and who are comfortable checking frame dimensions and doing a basic installation. It performs best when paired with a reliable 12VDC power source and used in an access control setup where either fail-safe or fail-secure behavior is required.

Customers who want plug-and-play convenience with vendor support for power troubleshooting, or who need a strike sized for an unusual frame without verifying measurements first, should look elsewhere. Also, purchasers expecting a lifetime of trouble-free operation without occasional maintenance on power supplies or cleaning may be disappointed.

Pros & Cons

Pros

• Sturdy alloy construction that feels well made and durable.
• Switchable fail-safe and fail-secure modes for flexible security policies.
• High impact strength and a rated cycle life suitable for commercial use.
• Compatible with both cylindrical and mortise locksets for retrofit projects.

Cons

• Requires verifying frame dimensions before ordering to avoid fit issues.
• Some users report mixed long-term reliability, and power supply problems can mimic strike failures.

Our Verdict

The Heavy Duty Electric Door Strike Lock is a pragmatic choice for installers and facility managers who need a robust, adaptable electric strike without premium pricing. Its rugged alloy build, switchable fail-safe and fail-secure modes, and high impact rating make it good value for retrofit projects, provided buyers verify frame size and supply steady 12VDC power.

Frequently Asked Questions

Can this strike be used with both cylindrical and mortise locks?
Yes. The design supports conversion of cylindrical locksets and use with mortise locksets in access control systems.

How do I change between fail-safe and fail-secure?
Loosen the designated screw and retighten it in the alternate hole to switch between Fail-Safe (NC) and Fail-Secure (NO) modes.

What if the strike stops working after installation?
Check the 12VDC power supply first; low or aging power supplies can cause failures. Also inspect and clean the coil area with a dry cloth to remove dirt before assuming the strike is defective.
