Check clearance around the window
Seal
The Perfect Fit framework needs a minimum of 6mm clearance all round the window frame.
Seals must not protrude over the glass by more than 6mm. If the seal is compressible, you can
take a ‘bead to bead’ measurement. If not, then take a ‘seal to seal’ measurement.

Measuring, assembly & fitting instructions

Measuring Glass Size
2
For more information on measuring, see Louvolite Perfect Fit measuring, assembling and fitting
instructions for pleated and venetian blinds.
Measure both the width and
the drop accurately.
We recommend the use of a
metal tape measure.
Measure both corners and the middle and use the smallest measurement taken.
Repeat the above step for the drop.

Window depth can be measured using a depth gauge (P9481). This gives you the measurement
from the face of window frame to the glass (normally range from 18mm to 24mm)
This will determine the size of the window fixing brackets required.
You can utilise the Perfect Fit survey sheet to record this information.

Intermediate punch holes will be required if the distance between punch holes is greater than
1500mm.
Punch Holes
Using the Clip hole Punch (P9476) place the side frame extrusion into the die, punching the
holes at pre-determined measurements to ensure the holes line up exactly with the brackets.

For punching the bottom of the
side frame ensure the stops are
set 64mm from the punch body.

For punching the top of the side
frame ensure the stops are set
38mm from the punch body.

Fitting Corner Joints
Secure the joints by tightening the 4
screws on each joint.
Assemble the bottom of a frame using 2 corner joints (R4026).
Do this by sliding the joints into
your frame section.

Place your roller blind tube into
this using the correct size slot
for the fabric thickness
Place your aluminium bottom bar
into the slot provided. Place the
small groove face up for single or
double wrap.
Place your fabric face up and
against the left hand straight
edge, overlapping your top tube
by approx 15 mm

Clamp down the fabric.
Starting at the right hand side of
your fabric. Use the creasing tool
and forming tool to form the fabric
into the groove on your tubing.
From the Mylar punch, pull a length
of fabric locking tape (FLT) to the
width of your blind and press down
onto the punch to cut it.
Please note: There are 3 sizes of FLT
6,7,8mm that can be used dependant
on the thickness of fabric.

Return to the right hand side of
the blind and hook the FLT to the
hook on your forming tool
Pull the FLT through the tube
Cut off any excess fabric that
appears along the tube.
Release the clamp bar and cut off
any excess FLT on both ends.

Release the clamping arm and
then turn your fabric and bottom
bar forward 180 degrees and
replace back into bottom bar
groove.
Crease form and insert FLT into
this groove then cut off any
excess fabric.
Remove from bottom bar groove
and cut off any excess FLT.
Turn your fabric 180 degrees
clockwise and place against the
left hand straight edge and
overlapping the bottom bar by
70mm and then clamp down the
fabric.
Crease, form and insert the FLT,
as previously done into the
groove on your bottom bar

Attaching the Appropriate Handle
Plastic Handle
On the face side of your bottom
bar find the middle distance and
fit the back plate of the handle
to this using the screws provided
Then place your handle at 90
degrees to this and twist on
anticlockwise

Metal Handle
This handle slides into the
top groove of the bottom bar
and should be positioned in
the middle

Slide the spring onto the
spring drive unit.
Once assembled, slide the roller
blind over the spring assembly
until it will go no further.

Before the leg is all the way in, ensure
that the bush on the corner joint lines
up with the top tube.
Final Frame Joint
The simplest way to do this is to slide
the leg of the corner joint into the
curved section.
Slide the curved section into the spring end and then the remaining corner joint needs to be
lined up with the top tube and the curved section.

Fitting Curved Top Section
For white and brown frames:
Slide top of curved section into the rest of the
frame. Add ‘Wrap Tension’ (see page 17 for
instructions).
Once ‘Wrap Tension’ has been applied ensure
that end caps are located into the side channel.
Fix securely with the two
screws on each joint.
Fix one side in position at a slight angle then place the opposite side into position.
Please ensure that the bottom bar sits behind the grooving.

Adding ‘Wrap Tension’
5. Push the worm retaining clip into
the hexagon slot to secure the tension.
In order for the fabric to roll up, we need to add ‘wrap tension’ at the top of the blind.
1. Pull down the blind (do not
manually push back up as it
needs to raise naturally with the
tension)
2. Insert a 4mm allen key or a
power tool, or an angled allen
drive attachment (R9002 as
shown) into the hexagon slot in
the control end
3. Turn ‘anti-clockwise’ to add
tension until the blind starts to
lift.
4. Tension is complete when the
blind is fully opened.
(i.e. all the fabric is wrapped
around the roller)

Last of all, ensure that the blind end caps fit into side grooves. Fit all corner joint covers into
position and your blind is finished.
Finished Blind

Line up the bracket with the base or top of the credit card (depending on which corner of the
window you are working) and fit the bracket by pushing it between the glass and the rubber seal
of the window.
Repeat for all 4 corners of the window, and intermediate brackets (if required) then clean excess
lubricant prior to fitting the frame.
Fitting Perfect Fit
Line up bracket with edge of card
19
To ensure all brackets are in the correct position for fitting (85mm from beading) use a credit card
in the corner of the window to locate the bracket position.
For ease of insertion, use a lubricant in the form of washing up liquid on the base of each bracket.
