How to Fit and Remove Perfect Fit Blinds: Step-by-Step UK Guide
- by 1Click Blinds
To fit perfect fit blinds, slide the four metal brackets into the gap between the glass and the rubber seal of your uPVC window (two at the top, two at the bottom), then clip the blind frame onto the brackets. To remove them, unclip the frame from the brackets and slide the brackets back out of the seal. Neither job needs a drill, screws or tools, and most windows take 15 to 30 minutes.
This guide covers how perfect fit blinds work, how to fit them step by step, how to take them down without damaging the window seal, how to open the window with the blind fitted, and how to clean them. It works for perfect fit metal, wooden and pleated blinds and for perfect fit shutters, which all use the same clip-in system.
Quick answer
| Job | What you do | Time | Tools |
|---|---|---|---|
| Fit | Slide 4 brackets behind the seal, clip the frame on | 15 to 30 minutes per window | None (a plastic scraper helps on tight seals) |
| Remove | Unclip the frame, slide the brackets out | About 5 minutes per window | None |
| Clean | Dust, or unclip and wipe flat | A few minutes | Microfibre cloth |
How do perfect fit blinds work?
A perfect fit blind is a normal blind (venetian slats, pleated fabric or shutter louvres) built inside a slim aluminium frame. The frame is made to the exact size of one pane of glass. Instead of being screwed to the wall, it hangs on four small metal brackets that grip the window itself.
Every uPVC window has a strip that holds the glass in place, called the glazing bead, with a rubber seal against the glass. The brackets have a thin flat tongue that slides into the tiny gap between that seal and the glass, then hooks over the bead. The frame clips onto the brackets, so the blind sits flat against the glass, about the depth of the bead away from it.
Because the blind is fixed to the window and not the wall, it moves with the window when you open it. That is why perfect fit blinds are the go-to choice for tilt and turn windows, French doors and bifold doors.
| Part | What it does |
|---|---|
| Glazing bead | The uPVC strip around the glass. The brackets hook over it. |
| Rubber seal | The black or white rubber against the glass. The bracket tongue slides behind it. |
| Brackets (4) | Two at the top, two at the bottom. Chosen to suit your bead depth. |
| Frame | Holds the blind and clips onto the brackets. |
Bead depth matters because the brackets have to hook over the bead neatly. That is why you measure it when you order. See how to measure perfect fit blinds without getting the bead wrong.
Before you start
- Check the window: perfect fit blinds need a uPVC window or door with a rubber seal behind the glazing bead. Aluminium or wooden frames without that seal need a different blind.
- Check you have the right blind: each blind is made for one pane, so match the label or size to the right window.
- Clean the glass and seal: wipe away dust so the brackets slide in smoothly.
- Find the handle side: on tilt and turn windows and doors, the controls or tilt rod should be on the side away from the handle.
- Have to hand: a plastic scraper or old bank card, and a little washing-up liquid if the seal is tight.
How to fit perfect fit blinds: step by step
- Hold the frame against the glass to see where the brackets will go. The top brackets usually sit near each top corner and line up with the hooks or slots on the back of the frame.
- Slide in the top brackets. Push the flat tongue of each bracket into the gap between the rubber seal and the glass, then press it down so it hooks over the glazing bead. If the seal is tight, open the gap slightly with a plastic scraper or old bank card, or wipe a tiny drop of washing-up liquid on the tongue.
- Slide in the bottom brackets the same way, lined up with the top ones so the frame will hang straight.
- Hang the frame on the top brackets. Tilt the frame slightly and hook the top of it onto the top brackets.
- Clip in the bottom. Push the bottom of the frame gently towards the glass until it clicks onto the bottom brackets.
- Check it. Raise and lower the blind or tilt the slats, then open and close the window to make sure nothing catches.

Fitting tips
| Problem | Fix |
|---|---|
| Bracket will not slide behind the seal | Ease the gap open with a plastic scraper and add a tiny drop of washing-up liquid. Never use a metal knife. |
| Frame does not reach the bottom brackets | Move the bottom brackets up or down slightly so they line up with the frame. |
| Frame looks crooked | Check the top brackets are at the same height and push each one fully down over the bead. |
| Blind rattles when the window closes | Push the bottom of the frame firmly until it clicks; check all four brackets are fully seated. |
| Handle hits the frame | The blind may be on the wrong pane; check the size. On tilt and turn windows the frame sits inside the bead and should clear the handle. |
How to remove perfect fit blinds
You might need to take perfect fit blinds down to clean them, to clean the window, to replace a blind or to take them with you when you move. They come off without tools and without marking the frame.
- Raise the blind or open the slats so you can see the brackets.
- Unclip the bottom of the frame. Hold the bottom rail and pull it gently towards you, away from the glass, until it releases from the bottom brackets.
- Lift the frame off the top brackets. Tilt the bottom out a little, then lift the frame up and off.
- Slide out the brackets. Hold each bracket by the part that hooks over the bead and pull it straight up and out of the seal. Wiggle it gently from side to side if it is tight.
- Check the seal. Press the rubber seal back into place with your finger if it has lifted.
- Keep the brackets in a labelled bag with the blind, so you can refit it later.
Only want to clean the blind? Do steps 1 to 3 and leave the brackets in the window. Clipping the frame back on takes seconds.
Will removing perfect fit blinds damage the window?
No, not if you pull the brackets out straight and do not lever against the glass with metal tools. The brackets do not cut or screw into anything, so there are no holes to fill. This is why perfect fit blinds are so popular with renters. Read do perfect fit blinds damage window seals? The honest answer.
Can you open the window with perfect fit blinds fitted?
Yes. The blind is fixed to the window sash, not the wall, so it opens, tilts and turns with the window. You never have to move the blind out of the way. This is the main reason people choose perfect fit for:
- Tilt and turn windows, which open inwards
- French doors, which swing open into the room
- Bifold doors, which fold back on themselves
How to clean perfect fit blinds
| Blind type | Regular clean | Deep clean |
|---|---|---|
| Perfect fit metal | Close the slats, dust with a microfibre cloth, tilt the other way and repeat | Unclip, lay flat, wipe with warm soapy water, dry |
| Perfect fit wooden | Dust with a dry cloth or soft brush | Barely damp cloth only, dry straight away. Never soak. |
| Perfect fit pleated | Vacuum gently with a brush attachment | Spot clean with a barely damp cloth |
| Perfect fit shutters | Close the louvres, dust, tilt and repeat | Unclip, lay flat, wipe with a barely damp cloth, dry |
Unclipping the frame (steps 1 to 3 above) also lets you clean the window glass behind it. More tips in how to clean venetian blinds.

Frequently asked questions
How do you fit perfect fit blinds?
Slide two brackets behind the rubber seal at the top of the glass and two at the bottom, hook the frame onto the top brackets, then push the bottom in until it clicks onto the bottom brackets.
Do you need tools to fit perfect fit blinds?
No. A plastic scraper or old bank card helps ease a tight seal, but you do not need a drill, screws or a screwdriver.
How do you remove perfect fit blinds?
Pull the bottom of the frame towards you to unclip it, lift the frame off the top brackets, then slide each bracket straight up and out of the seal.
Can you take perfect fit blinds off to clean them?
Yes. Unclip the frame and leave the brackets in place. Clean the blind flat, then clip it back on.
Can I reuse perfect fit blinds in another house?
Yes, if the new windows have the same glass size and a similar bead depth. Keep the brackets with each blind.
Why will my perfect fit bracket not go in?
The seal is tight against the glass. Ease the gap open with a plastic scraper and add a tiny drop of washing-up liquid to the bracket.
Do perfect fit blinds damage window seals?
No. The brackets slide behind the seal without cutting it. If the seal lifts when you remove a bracket, press it back into place.
Can you open a window with a perfect fit blind?
Yes. The blind is attached to the window, so it opens, tilts and turns with it.
Do perfect fit blinds work on all windows?
They work on uPVC windows and doors with a rubber seal behind the glazing bead. For other frames, choose an Easy Stick blind or a screw-fit blind.
How long does it take to fit perfect fit blinds?
Most windows take 15 to 30 minutes. Once you have done one, the rest are quicker.
Can perfect fit blinds fall off?
Not when all four brackets are fully seated over the bead and the frame has clicked in. If a blind feels loose, push each bracket fully down and re-clip the frame.
