At my church, we have four doors that lead to the chapel. Fire doors (good
wood), with surface mounted panic hardware.
the vertical rods rattle like crazy when anyone opens one of the doors.
Folks got to get in and out to take screaming babies out. And the rattling
I forgot to check which brand, model, etd. any ideas how to quiet this?
If you can get the brand, a note to the manufacturer might be a good
place to start.
If not... Least-risk thing I can think of would be to introduce some
kind of padding behind the rod to gently muffle it without interfering
with motion. But I'd say check with local authorities before making ANY
change. As you said, this is fire hardware, which means codes are Really
is it not possible to DOG the handle down, so the rods are
disengaged, while church is going on?
look for a hex UNDER the handle, where it mounts to the door..
some have these, and some do not..
if there is a key lock on the OUTSIDE, is it possible to lock
the door OPEN? thereby holding the rods from engaging?
Usually on the rods there is a midway support. This might be designed to
have a nylon bushing that is missing. Also check out the upper and lower
latch. Often they have rubber bits inside that are worn missing or dried
For many years I worked as a carpenter for a contractor who did
interior trim and finsih hardware in commercial construction. During
the eighties and early nineties, we installed the trim, doors and
hardware in many Mormon churchs throughout northern California and
came across this complaint often after the church had moved into the
The standard specs the church used at the time allowed for Von Duprin,
Yale, Monarch,Precision,and the ever popular "architect approved
equal" exit devices.
I think you can guess which ones were installed most often. The only
solution the church in this area could come up with was to bite the
bullet and replace the Monarch and Precision units with Von Duprin
units, which are much quieter due to the dampner that softens the
release or rebound of the bar.
You won't be able to dog these devices open if they are on interior
doors, because they are a fire rated device and as such have no
provision for dogging.
Hope this helps,
That's probably it. My suggestion would be to have your distributor special
order the bushings. In the mean time you might try *temporarily* wrapping a
layer or two of electrical tape around the vertical rods right where they go
through the guides. Just one or to wraps around the rod should be enough
to dampen the rattle but not cause them to bind.
Mind you... This is only a temporary fix unless you want to keep replacing
the electrical tape every few months on the most active doors.
Or a block of delron (white plastic) and make your own.
Sources: Olympus 700 locks used to come with blocks of white plastic for
"spacers" lots of great uses for these.
The white plastic cutting boards like those used in restaurants are cheep
and available anywhere walmart, restaurant supply, home depot, lowes ect
While using a factory part is appropriate, you need not check your common
sense at the door. A nylon bushing from the hardware store just takes up
the slack like the factor bushing, and is probably cheaper by a long shot.
This is in the same category as using a screw from the hardware store rather
than the ones the factory sells as parts. 8 cents vs. $2.50.
