In

of

or

They

of
a

Deadbolts
can
be
a

Door
Stop:
A

is
the

1
3/8"
-
1
1/2"
wide,
that
is
attached
to
the
door
jambs
on
both
sides
and
on
top
of
the
door.
This
strip
of
wood
is
where
the
door
comes
to
rest
when
it
is
closed.
It
stops
the
door
from
moving
any

and
also
covers
the
gap
that
would
otherwise
appear
between
the
door
and
the
jambs.

that
is
inserted
into

to
magnify
an

on
the
other
side
of
the
door.
Viewers
are
made
with
various
degrees
of
field
of
vision.
Dummy
Pairs:
Dummy
pairs
are
for
doors
where
no
latches
are
needed.
These
knobs
or
levers
do
not
turn.
They
can
be
split
up
for
bi-fold
door
set,
since
no
hardware
is
needed
on
back
of
the
bi-folds.
Dummy
pairs
can
also
be
used
on
double
french
door
units,
where
ballcatches
are
used
to
hold
doors
in
place.
Dummy
Pairs
do
not
require
a
standard
hole
to
be
drilled,
since
most
are
attached
from
each
side
of
the
door.
Finials:
Also
called
decorative
tips,
these
may
come
in
different
shapes,
such
as
balls
or
pointed
steeples,
which
attach
to
the
top
and
bottom
of
a
hinge
for
decoration.
Only
some
hinges
will
accept
these
finials.
Flush
Bolts:
Bolts
mounted
in
a
door
to
lock
a
door
in
place.
These
bolts
slide
up
into
the
jamb
above
the
door,
and
down
into
the
threshold
or
floor
below
door.
These
are
used
primarily
on
double
doors,
where
one
door
is
locked
in
place
and
the
other
door
is
the
one
mainly
used.
When
needed,
the
door
locked
in
place
can
be
opened.
Flush
bolts
can
also
be
called
slidebolts,
which
are
mounted
to
the
face
of
the
door.
Flush
bolts
are
mounted
flush
with
the
edge
of
the
door.
