Each
of
the
Alouette®
Light
Louvers
operating
systems
described
below
will
work
in
standard,
easily
accessible
windows-in
which
case,
your
preference
is
the
deciding
factor.
Often,
however,
window
location,
size
and
other
considerations
can
narrow
your
choices.
BTS
(Bar-Tab
System)
-
The
louvers
are
tilted
using
a
tilt
bar
and
raised
using
a
lift
tab.
Offers
a
unique
look
in
the
window.
Cordless
design
is
ideal
for
homes
with
children
and
pets.
Excellent
for
doors
to
avoid
swinging
cords
and
tassels.
BCS
(Bar-Cord
System)
-
The
louvers
are
tilted
using
a
tilt
bar
and
raised
using
a
lift
cord.
The
tilt
bar
retains
a
shutter
look,
while
the
lift
cord
allows
easier
access
than
the
lift
tab
for
high
or
hard-to-reach
windows.
The
tilt
and
lift
controls
may
be
on
the
same
side
or
on
opposite
sides.
CCS
(Cord-Cord
System)
-
The
louvers
are
tilted
using
a
tilt
shuttle
and
raised
using
a
lift
cord.
The
cords
can
be
any
length,
so
this
system
is
perfect
for
high
windows
- as
well
as
for
center
windows
with
no
mounting
surface
for
a
tilt
bar
pivot
bracket.
The
tilt
and
lift
controls
must
be
on
opposite
sides.
