Door Knobs vs Lever Handles: How to choose?
hi my name is carl from the sunflash
company and this could be a little video
here just to
help you with the decision making
process whether you're going to be
choosing
door knobs or lever handles for your
project
there's a lot to consider and it's very
important that you do take a little bit
of time to think about it
this is mainly prompted from a
conversation i had last week one of my
customers
husband and wife team and they had two
toddlers in the house and they had
an elderly mother with arthritis now the
issue they have was
all our doorknobs are unsprung so we
have to use a thing called an
architectural tube electricity
it is a heavy sprung latch and if you're
a standard teenager adult you wouldn't
even notice that they're quite
quite stiff to turn but with toddlers
and somebody who's
much older with underlying arthritis
arthritic condition
um both ends of the spectrum couldn't
actually properly turn the doorknob
without some discomfort
so in reality perhaps they would have
considered that's going over to a
lever handling stem we've got more
purchase
so yes with regards to the doorknob
here is the second thing you've got to
be quite careful about
if you're replacing a
lever handle with a doorknob just be
very careful generally speaking a lever
handle
is much closer to the door frame because
the handle is
in effect taken away from the door edge
so
typically you have a tubular latch maybe
a two and a half three inch back set
the handle sits over the side of that
and the handle then taken away from the
edge
you remove the handle put a door
doorknob there especially if it's quite
wide
what you'll find is there's a good
chance if you're working for two and a
half inch back set
you're gonna be scraping your knuckles
on the uh on the
edge of the door and without further ado
let's get a little bit closer here and
see what we're dealing with
in front of us here right now we have a
fairly typical configuration for lever
handles
and for our unsprung door knobs so with
a lever handle here
typically you'll have inside here a
spring
held with a circlip so what you have
there you have two handles with two
springs
and then you have the tubular latch
which you have a much softer mechanism
so within here
will be a very light spring just enough
to let that
return with ease and the idea behind
that is you don't require
a heavy spring when you have two more
either side
and typically a lever handle the
distance between
there and there which is called the back
set will be a lot shorter than the
doorknob
obviously with the handle your hands
taken away the door off your hat you
have to go over it
here we have one of our four-inch
architectural heavy-duty
tubular latches inside here there are
two springs
one spin which operates this end here
another one
internally which operates the resistance
on this particular one here
now important to take into consideration
this one here the fact that
these knobs here are unsprung so there
is nothing within this knob to
retract it so they rely purely on that
again like i say
it it could feel a little bit difficult
a bit older or very
very young um other things that could
take consideration this particular knob
here is that you've got this these two
little cutouts here and these cutouts
here
are for um what we call bolt through
connections if you had like a lever on
rose handle
or a a door knob where you had
in effect a bolt through connection the
plate comes off
the handles go either side or water spa
you then bolt together
and then cover with a concealed fixing
thank you for watching i hope you found
this useful and it's helped you with
your decision process
regarding what kind of handle or not to
use um we have got for every product we
use we've got um some resources like for
example
on the dimensions tab you'll find force
at the working drawings
if you're an architect or a designer
we've also got a dwg file you're more
loved to download and using your files
thank you for watching and look out for
more
