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


door knobs or lever handles for your


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


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


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


is much closer to the door frame because

the handle is

in effect taken away from the door edge


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


you remove the handle put a door

doorknob there especially if it's quite


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


and for our unsprung door knobs so with

a lever handle here

typically you'll have inside here a


held with a circlip so what you have

there you have two handles with two


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


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


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


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
