Flush Bolts and Coordinators

Decoded: Manual Flush Bolts (March 2011)

This post was printed in the March 2011 issue of Doors & Hardware [Click here to download the reprint of this article.] One of the gray areas the door and hardware industry has struggled with is the use of manual flush bolts on pairs of doors in a means of egress.  The language in NFPA […]

WW: Down at the DMV

I find the Department of Motor Vehicles so frustrating that one year I actually cried because after waiting over an hour they said I didn’t bring the right utility bill.  AND…my car got hit by someone taking his driving test in the parking lot (he failed).  It might have all been worthwhile if I could […]

WW: “Leave them LOCKED!”

In case you have a hard time reading the sign on the LHR leaf, it says “Please do not use these doors.  Leave them LOCKED!”  🙁 Thank you to Eric Rieckers of Yadon Construction Specialties for the photo, even though it made me sad.  Keep ’em coming!

Decoded: Flush Bolts and Coordinators (January 2017)

A common question is whether an inactive leaf that is provided for convenience, aesthetics, or movement of equipment, and not required for egress is allowed to have manually-operated flush bolts…

FF: Storage Room Pair

I wish I had a nickel for every storage room door like this one I’ve seen. The flush bolts end up breaking through (as evidenced by the lovely repair to the bottom bolt area), and in this case the strike is gone too…

Fire Door Latching

In order for a fire door assembly to perform as designed and tested, it’s critical for the door to be closed and latched if/when a fire occurs…

FF: Zip It

Colin Watson of Allegion sent me this Fixed-it Friday photo of a surface bolt. Zip-tied for extra security. In a school. I guess they don’t want anyone using that leaf.

FF: Double Bolts

I recently ran across a Facebook page that could supply us with Fixed-it Friday photos until the end of time (or until I retire).
