Door Swing Primer

Author: Brian Rhodes, Published on Aug 21, 2013

The direction a door swings might seem minor, but it can greatly impact door hardware selection. There are four basic ways a door can swing, and knowing how to properly describe it is critical when designing access control systems and ordering door hardware. In this note, we lay out how to describe doors based on this subtle but divisive characteristic.

Brian,

Magnificent article. I would say that only about 1 in a 100 access control techs know about door handing, so readers of IVPM who read and understand this will have a significant advantage.

(To be honest, after more than 25 years in specifying hardware, I sometimes forget myself, and need to look at a "cheat sheet" that I have printed on the back of my door survey forms...)

...and inadvertently omitting them from a job estimate can cost hundred or thousands in additional hardware and labor.

I'm assuming that means that the L+Z bracket takes significantly more time than just the L, yes/no?

No, but installing brackets may not always be clean and easy depending on the frame dimensions or how crowded they might already be with common door equipment requiring clearances like closers.

I have seen single doors require significant extra work because the swing direction did not consider mounting the maglock properly on the frame.
