Flush Bolts and Coordinators
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 […]
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 […]
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! You need to login or register to bookmark/favorite […]
Flush bolts are used on pairs of doors to secure the inactive leaf, projecting into the frame head and into a floor strike. In this application, the active leaf would typically have a lockset which latches into a strike mounted on the edge of the inactive leaf…
I hope this whiteboard animation video helps to explain one of hardware’s most confusing topics – flush bolts and coordinators!
Manual flush bolts on pairs of fire doors leading to rooms not normally occupied by humans? WWYD?
I’ve had several situations where an AHJ interpreted the term “bolt lock,” used in the International Building Code (IBC), to mean a deadbolt…
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…
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…
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…
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.
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).
These doors are serving a church, and currently have key-operated deadbolts at the bottom of each leaf. The deadbolts are too low for the reverends to reach comfortably.
What’s a UHP? An Unidentified Hardware Product that I need your help to identify. But first, a note about spam – and not the canned ham-like version.
When a pair of fire doors has manual flush bolts and no closer on the inactive leaf, is a coordinator required?
This is the door hardware equivalent of whodunnit…maybe I should start calling these “whydunnit.”
