Access Strike Selection Guide

By Brian Rhodes, Published Aug 25, 2021, 10:25am EDT (Info+)

Despite being one of the most common access control components, specifying the right electric strike can be deceptively complex.

Understanding the particulars of each device can be overwhelming. In this note, we examine how strikes work, the tradeoffs in their specification, and how using them compares to other access lock types:

  • Strike Operation Described
  • Strikes DO NOT Add Security
  • Two Main Strike Types, Mortise vs. Surface
  • Strikes Typically Fail-Safe/Fail-Secure Changeable
  • AC or DC Powered and Noisy vs. Silent Tradeoff
  • Door/Latch Monitoring Importance
  • Strike Prices
  • Why Extra Hardware Is Often Needed
  • Installation Difficulty vs. Maglocks
