Q, What are
the different types of door handles?
A, There are 5 main handle types they
are:
Lever latch door handle on a backplate
Lever lock door handle on a backplate
Bathroom door handle set on a backplate
Privacy door handle on a backplate
Lever on a rose
Lever latch door handle
on backplate This is your basic door handle on a backplate
generally used on doors that you don't need to lock such as the living room or
dining room. It consists of a handle/lever on a backplate which when pushed
down turns the spindle which passes through the door and the tubular latch
inside the door allowing the door to be opened
This door handle is exactly the same as a lever
latch as above but it has a key hole cut out of the backplate below the
handle/lever to allow a key to be entered into the door to operate a sash lock
inside the door. This handle is commonly used on a back door or a patio door or
perhaps an office door.
Bathroom door handle set on a backplate The bathroom door handle has a thumb turn
sometimes referred to as a turn and release or a snib and release below the
handle, this is attached to a 5mm spindle which passes through the door and a
bathroom lock inside the door allowing the door to be locked and unlocked. As
the name suggests this handle is commonly used on bathrooms and toilets.
Privacy door handle on a backplate
The privacy set door handle has a thumb turn sometimes referred to as a turn
and release or a snib and release below the handle, when this is turned it
operates a mechanism behind the backplate which stops the handle/lever being
pushed down. Ideal for use on bedrooms or bathrooms. The privacy set is only
available in a few handle designs such as the victorian scroll suite, victorian
straight suite or the georgian suite. The privacy set only requires a tubular
latch in the door.

Tubular Latches
A tubular latch sometimes referred to as a mortice latch is used in
conjunction with either a lever latch door handle, a lever on rose or a
privacy door handle. They come in sizes ranging from 63mm (this refers to the
full length of the latch) upto 150mm. The length of the latch will determine
the positioning of the spindle at the centre of the door handle or door knob
(this distance between the edge of the door and the hole in the latch which
takes the spindle is referred to as the backset) Some tubular latches have
holes in the body of the latch to allow bolts to pass through them when
fitting handles with back to back bolt through fixings.
Rollerbolt Latches
Rollerbolt latches are commonly used on doors where you wish to fit a
cupboard knob or a pull handle. The roller slots into the striker plate in
the door frame to keep the door in the closed position, the spring can be
adjusted for varying the force needed to open and close the door.
Sash Locks
Sash locks also known as mortice sash locks are used on doors you wish to
lock with a key. They can be used in conjunction with a lever lock door
handle on backplate, a door lever on rose and a key hole escutcheon
combination or a door knob and escutcheon combination. They come in sizes
63mm or 75mm (this refers to the full length of the lock casing). The length
of the lock will determine the positioning of the spindle at the centre of
the door handle or door knob (this distance between the edge of the door and
the hole in the lock which takes the spindle is referred to as the backset)
Some locks have holes in the body to allow bolts to pass through them when
fitting handles with back to back bolt through fixings.
Bathroom Locks
Bathroom locks are used bahrooms. They can be used in conjunction with a
bathroom door handle set on backplate, a door lever on rose and a turn and
release combination or a door knob and turn and release combination. They
come in sizes 63mm or 75mm (this refers to the full length of the lock
casing). The length of the lock will determine the positioning of the spindle
at the centre of the door handle or door knob (this distance between the edge
of the door and the hole in the lock which takes the spindle is referred to
as the backset) Some locks have holes in the body to allow bolts to pass
through them when fitting handles with back to back bolt through fixings.
Dead Locks
Dead locks also known as mortice dead locks provide extra security to the
external doors of a property often fitted to a wooden front door in
conjunction with a night latch. They come in 63mm or 75mm (this refers to the
full length of the lock casing). The length of the lock will determine the
positioning of the key hole.
Rim Locks and rim latches
Rim locks and rim latches are fitted on the face of the door and need to be
fitted in conjunction with a rim knob. This type of lock and latch system is
commonly seen in older period cottages.
The rim lock incorporates a latch which is operated by turning the knob to
open the door and a key which operates lock from both sides of the door which
shoots into the keep fitted to the edge of the door frame The rim latch does
not have a key but instead it has a button which is pushed accross with the
finger to lock the door from one side.
