Door Furniture Terminology FAQ
Q. What is meant by the term
"lever lock" handles?
A. Lever lock handles have a key hole cut into the back plate. They are
used in conjunction with a mortice sash lock and allow the door to be locked by
means of a key. The mortice sash lock is usually 2.1/2" or 3" wide and
is not supplied complete with the handles, they need to be purchased as a
separate item. Locks are available with different levels of security as required
by the situation to which they are fitted. The lock is mortised into the
edge of the door and the locking bolt is operated by the key through the key
hole in the handles, the latch is operated by the lever on the handles. The face
plate on the sash lock is normally specified to have a matching finish to the
handles.
Q. What is meant by the term
"lever latch" handles?
A. Lever latch handles have a plain back plate. They are used in
conjunction with either a mortice or tubular latch which is normally 2.1/2"
or 3" long, although longer sizes can be obtained if the handles need to be
placed further in from the door edge. The latch is mortised into the edge
of the door and is operated by depressing the lever on the handle. It is not
supplied complete with the handles, but needs to be purchased as a separate
item. The face plate on the latch is normally specified to have a matching
finish to the handles. Tubular latches, the most common type of latch, offer the
same function as mortice latches and are easier to fit. Mortice latches usually
have stronger springs which may be more suited to heavier or unsprung commercial
door handles.
Q. What is meant by the term
"privacy set" handles?
A. Privacy handles can be used on bathroom doors or where privacy is required.
On the inside of the door there is a turn button and on the outside of the door
there is an emergency release slot, usually operated by a coin, which can be
used to unlock the door in an emergency. These handles are normally used with a
tubular latch which is 2.1/2" or 3" long. When the turn button is
operated, the tubular latch becomes 'locked' and the bathroom door cannot be
opened, except by turning the button again or by using the emergency release
from the outside.
Q. What is meant by the term
"bathroom locking" handles?
A. Bathroom locking handles are similar to privacy set handles except
that they are used with a bathroom mortice lock rather than a tubular or mortice
latch. The turn and release are the same, but when turned, they operate a
deadbolt on the bathroom mortice lock rather than locking a tubular or mortice
latch. The bathroom lock is mortised into the edge of the door and is usually
2.1/2" or 3" wide. It is not supplied complete with the handles, but
needs to be purchased as a separate item and is normally specified to have a
matching finish to the handles.
Q. What is meant by the term
"euro profile" handles?
A. Euro profile handles have an enlarged key hole shape cut out of the
back plate. This euro cut out in the back plate is used to house a key operated
cylinder. The cylinder is used with a mortice sash lock fitted into the edge of
the door which also has the euro shape cut into it to allow the cylinder to pass
through the lock and come out on the opposite side of the door. These cylinders
come in various lengths depending on the thickness of the door and various
styles such as double key, key and turn, or single cylinder. When the key or
thumb turn is operated, the deadbolt on the lock is thrown and the door is then
locked. We supply two sizes of euro profile handles, 48mm and 57mm. The sizes
refer to the distance between the centre of the spindle and the centre of the
cylinder as dictated by the lock design.
Q. What is meant by the term
"oval profile" handles?
A. Oval profile handles have an oval shape cut out of the back plate.
This oval cut out in the back plate is used to house a key operated cylinder.
The cylinder is used with a mortice sash lock fitted into the edge of the door
which also has an oval cut into it to allow the cylinder to pass through the
lock and come out on the opposite side of the door. These cylinders come in
various lengths depending on the thickness of the door and various styles such
as double key, key and turn, or single cylinder. When the key or thumb turn is
operated, the deadbolt on the lock is thrown and the door is then locked.
