Propped Doors Access Control Tutorial

By: Brian Rhodes, Published on Sep 28, 2017

Doors should keep 'bad guys' out.

One of the most basic problems with doors is people propping them open:

Even worse, door propping undermines significant investments in electronic access control. The issue is especially frustrating to building security because it is so common and easy to pull off. In this note, we examine:

  • Convenience vs Security
  • Common reasons for doing so
  • Eliminate the means for door propping
  • Adding signage and education
  • Installing specialty equipment
  • Using door closers

Finally, we conclude with a 5 question quiz to test your knowledge.
