Buying Guide

Securing your space starts with the right tools. Fail-secure door strikes keep doors locked during power outages, giving you peace of mind.

Choosing the best fail-secure door strike is easy when you know what to look for. Here’s a simple guide to help you decide:

  • Strength and Durability:
    Look for strikes with high static strength (like 1000 lbs. or more). Strong materials like stainless steel or alloy ensure long-lasting use.

  • Fail-Secure vs. Fail-Safe:
    Decide if you want fail-secure (stays locked during power loss) or fail-safe (unlocks during power loss). Some strikes let you switch between modes.

  • Compatibility:
    Check if the strike works with your door type (metal, wood) and lock system (cylindrical, mortise). Versatile designs fit most setups.

  • Installation:
    Choose strikes that are easy to install with clear instructions and included hardware. Shallow designs often fit better.

  • Adjustability:
    Look for strikes with adjustable modes or horizontal adjustments for a perfect fit.

  • Power Requirements:
    Ensure the strike matches your power setup (like 12VDC or 24VAC). Dual voltage options offer flexibility.

  • Cycle Life:
    Pick strikes tested for high cycle counts (like 500,000 or 1 million uses) for long-term reliability.

  • Additional Features:
    Consider strikes with signal outputs or door position indicators for advanced access control.
