FRAME COMPONENTS
Made-to-measure frame or channel sections for the supplied window.
INSTALLATION GUIDE
FIT YOUR BLOCKER WITH CONFIDENCE.
Your BLOCKER is made for the measurements supplied with your order. The fitting process is designed to be clear and methodical: assemble the system, prepare the perimeter, position it in the recess, then test the blind and check the edges.
Unsure about your window, handles or recess? Contact us before fitting and send clear photographs of the opening.
BEFORE YOU FIT
CHECK THE WINDOW ONE MORE TIME.
Before unpacking every component, compare the supplied system with the window it was ordered for. Make sure the recess is clear, the window opens as expected and handles, locks or other fittings do not obstruct the position of the BLOCKER frame.
If anything looks different from the measurements or photographs used when ordering, stop and contact us before fixing the system in place.
- Confirm you are fitting the correct blind to the correct window.
- Check the recess is clean, dry and free from loose paint, dust and debris.
- Check handles and locks can still operate.
- Check the opening direction of the window.
- Have your original measurements available.
- Read the complete fitting sequence before starting.
YOUR BLOCKER KIT
EVERY PART HAS A JOB.
A perimeter blackout system works because the frame, blind and edge-control components work together. Lay everything out on a clean, soft surface before assembly. The exact parts supplied are listed in the guide that comes with your blind.
BLACKOUT BLIND
The made-to-measure blind panel supplied for your configuration.
PERIMETER SEALING
The edge-control components supplied with your production system.
FITTING PARTS
Connectors, caps, fixings or adjustment tools supplied with your system.
PART 1
BUILD THE FRAME ON A CLEAN, FLAT SURFACE.
Work methodically and avoid forcing any joint. If the production components are labelled, match the corresponding ends before connecting them.
-
1
Lay out the components
Place the side, top and bottom sections on a clean surface in their final orientation, with the blind section positioned as shown in your supplied instructions.
-
2
Identify the joining ends
Check any labels, locating features or connectors before pushing the sections together. The finished frame should stay square and the channels should face the correct direction.
-
3
Connect the frame
Join the sections using the supplied connectors. Work around the frame rather than fully tightening one corner before the others are aligned.
-
5
Check the corners
Make sure each corner is fully seated, square and flush. Fit any supplied corner covers only after the frame is correctly assembled.
Component-specific steps are supplied in the printed guide that comes with your blind, because they depend on the hardware in your order.
Poorly seated corners can create a visible path for light, so take time to make each joint neat.
PART 2
THE EDGES MATTER.
The point of BLOCKER is not simply to put opaque material in front of the glass. The perimeter system is designed to control the places where ordinary roller blinds leave open gaps.
-
1
Clean the contact surfaces
Wipe the relevant frame and recess surfaces so any supplied adhesive or sealing material can sit flat.
-
3
Form clean corners
Treat each corner as a separate seal. Aim for a neat right-angled meeting point without an obvious gap.
The exact strip type, order and corner technique are supplied with your blind. We are not publishing them here until the production components are confirmed.
PART 3
SEAT IT SQUARE. THEN CHECK THE CLEARANCES.
-
1
Offer the system up to the window
With the assembled system supported securely, position it in the recess using the method supplied with your BLOCKER.
-
2
Check the edges before final fixing
Look around the complete perimeter. The frame should sit evenly and should not foul handles, locks or the opening sash.
-
4
Test the window
Where the window needs to open, confirm it can still operate safely without striking the blind or frame.
The mounting method for your blind — and the surfaces it suits — is specified in the guide supplied with your order.
PART 4
OPEN. CLOSE. CHECK THE PERIMETER.
Operate the blind through its normal travel several times. It should move cleanly, sit correctly in its channels and close without needing excessive force.
-
1
The blind moves evenly
Through its full travel, in both directions.
-
2
The frame remains square
No corner has pulled out of alignment during fitting.
-
3
Nothing catches
No component rubs or snags as the blind travels.
-
4
Handles and locks still work
Where the window needs to open, it still operates safely.
-
5
Perimeter components stay seated
Nothing has lifted, stretched or pulled away at the edges or corners.
FINAL CHECK
LOOK FOR THE LIGHT, NOT JUST THE BLIND.
The easiest time to inspect the perimeter is during daylight. Close the blind, dim the room and look carefully around the top, sides, bottom and corners.
-
1
Identify the exact location
Top, side, bottom or corner — being specific makes it much easier to diagnose.
-
2
Check the frame is fully seated
A frame sitting proud on one side is the most common cause.
-
3
Check the perimeter strip
Look for anywhere it has lifted, stretched or pulled away.
-
4
Check each corner is properly formed
Corners are where light paths most often appear.
-
5
Contact us before modifying anything
Do not cut or alter components beyond the supplied instructions.
If you see an unexpected line of light, photograph the whole window and the affected edge before adjusting anything, and send it to us.
TROUBLESHOOTING
IF SOMETHING DOESN'T LOOK RIGHT.
The frame will not sit fully inside the recess
Check for handles, locks, vents, trim, uneven plaster or other obstructions. Do not force the frame — send us a photograph instead.
One corner will not close neatly
Recheck the frame joint and any perimeter strip at that corner. A badly seated joint can create an unwanted light path.
The blind feels too tight or too loose
Stop, and use only the adjustment procedure supplied with your blind. Forcing the mechanism can damage it.
I can see light around one edge
Check the frame is square and the perimeter components are fully seated. Photograph the complete window and the affected edge if you need support.
The window catches the BLOCKER frame
Do not continue operating the window against the system. Contact support with photographs showing the opening direction and the obstruction.
NEED A SECOND PAIR OF EYES?
SEND US THE WINDOW.
For fitting help, send clear photographs of the full window, the recess, the relevant corner or obstruction, and your order details. We can help you work out what to check next.
