Blackout Roller Blind with Clamp Brackets, No Drilling Required, Indoor Thermal Roller Blinds for Windows and Doors, 150 cm, 160 cm, 170 cm, Sun Protection and Privacy

Product Overview

A blackout roller blind that clamps onto the window frame instead of being screwed into the wall. Two clamp brackets grip the frame or the opening sash, the fabric rolls down from a slim aluminium tube, and the whole fitting is done without a drill — no holes, no plugs, no patching when the blind comes down again. For rented flats, leased offices, serviced apartments and show homes, that single change removes most of the friction of fitting window coverings.

We build these blackout roller blinds in 150 cm, 160 cm and 170 cm widths for wide windows, balcony doors and sliding glass, and the same hardware takes either a blackout fabric or a daylight fabric. The blackout option is a dense, opaque weave with a silver-coated reverse, so it works on light and on heat at the same time; the daylight option keeps the room bright while softening direct sun.

Day to day, you pull the side chain and the fabric stops wherever you leave it. Rolled up, only a slim roll of fabric sits above the glass, so sills, curtains and door handles stay clear. Installers choose these no drill roller blinds when a whole floor has to be fitted in a morning without touching the plaster, and facilities teams choose them because they come off just as cleanly at the end of a tenancy.

Specifications

Light Control & Privacy

• Around 95% light blocking on the standard fabric. Street lamps, a neighbour's security light and the early sun of a summer morning are what wake most people up. The blackout weave takes the bulk of that away, which is why these blackout roller blinds end up in bedrooms, hotel rooms and media rooms first.
• The last few percent at the edges. No fabric-only blind seals a window completely — a narrow band of light still passes at the sides and along the bottom bar. Mounting outside the recess with a small overlap on each side, or dropping the blind past the sill, removes most of it.
• Daylight fabric when the room should stay bright. Same rail, same brackets, a lighter weave that keeps the view and turns hard sun into a softer light. It is the practical choice for living rooms, kitchens and offices where total darkness would feel wrong.
• Privacy in both directions. The opaque face stops silhouettes and interior shapes being read from the street at night, and stops the room being overlooked by day. Because the fabric hangs flat at the glass line rather than folding, there is no gap to see through.
• Heat, not only light. The silver-coated reverse reflects radiant heat back into the room in winter and away from it in summer, which takes the edge off a glazed wall in a way a thin decorative blind cannot.
• Glare on screens. A home office facing the sun loses half its working day to reflections. Dropping the blind to eye level cuts the glare and keeps the monitor readable without turning the room into a cave.

Fabric & Build Quality

Material is where a substandard blind gives itself away, usually in the second summer rather than the first. We cut from tear-resistant polyester as the standard, with waterproof PVC and cotton-linen blends available when the job needs them. Every option is moisture-proof and stain-resistant, so a kitchen splash or a bathroom's humidity does not leave a mark or a lingering smell behind.

The face of the blackout fabric is a matte woven textile rather than a glossy sheet, and the reverse carries the silver coating that does the thermal work. That combination matters on window roller blinds that sit in full sun all afternoon: the colour holds, the fabric does not go brittle, and the blind still hangs flat instead of curling at the bottom corners.

The tube is rust-proof aluminium, and the bottom bar is matched to whichever top rail profile you choose, so the fabric hangs square and the hem stays straight even across a 170 cm width. The clamps are metal-bodied rather than plastic, because the bracket is the part that carries the entire blind.

Wipe-clean is not a marketing line here. Dust and finger marks come off with a damp cloth and a drop of mild soap — no soaking, no taking the blind off the brackets, and no dry cleaning.

Clamp-Mount Installation

1. Check the frame before you order. The clamps need a flat, solid face on the frame or opening sash, and enough depth for the bracket to sit squarely. Send a photo of the frame profile and its depth with your order and we will confirm the bracket for it.
2. Slide the brackets onto the top rail. Both clamps go on the rail first, before the blind goes anywhere near the window.
3. Set the spacing. Position the brackets in from each end so the fabric pulls down evenly across the width; on a 150 cm or 170 cm blind, a bracket set too far inboard lets the rail flex.
4. Seat the clamps on the frame. Open each clamp, hook it over the frame face and close it. No plugs, no screws into the wall, nothing to fill afterwards.
5. Tighten by hand. Finger-tight is enough. Over-tightening distorts the clamp and marks soft timber frames.
6. Hang the fabric and check the drop. Roll the blind down to the sill and back up once, watching that the fabric runs parallel to the frame rather than drifting to one side.
7. Anchor the chain. Fit the child safety clip to the wall or frame and run the chain through it so the loop is held taut and out of reach.
8. Re-check after a week. Clamps settle slightly on timber and uPVC; a further quarter turn after the first week is normal and keeps no drill roller blinds sitting tight for the season.

Quiet Chain Operation

• Built for the weight of a blackout fabric. Blackout blinds carry more weight per square metre than a sheer or a daylight weave, so the chain runs on a clutch sized for that load — the pull stays light even on a 170 cm drop.
• Holds exactly where you leave it. No creeping down an inch an hour and no tying the chain off; the blind stays at the height you set until you move it.
• Quiet in an occupied room. The chain runs over a clutch rather than a dry metal-on-metal roller, so there is no squeak or judder as it travels — the sort of detail that matters in a hotel room or a nursery.
• Child safety clip as standard. The chain loop is anchored to the wall so it cannot swing free. Fit it, and keep the loop above the reach of small children.
• Tell us which side you want the chain on. Left or right is set at assembly, so confirm it on the order rather than at the window.
• One hand is enough. A single downward or upward pull moves the blind, leaving the other hand free for a window handle or a door being held open.
• Rolls up out of the way. On black out roller blinds fitted above a balcony door, the fabric rolls into a compact headrail with enough clearance for the door to swing underneath.

Widths & Measuring

Three standard widths — 150 cm, 160 cm and 170 cm — cover most of the wide openings we are asked about: full-height balcony doors, patio sliders, large bedroom windows in newer builds, and the glazed frontages on offices and treatment rooms. All three are cut to a standard drop; if your opening needs a different one, that is a normal request rather than a special project.

Measure the width at the top, middle and bottom and work from the narrowest figure, because frames are rarely perfectly square. For an inside mount, measure the recess and take a few millimetres off so the fabric clears the frame; for an outside mount, measure the frame face and add an overlap on each side so the edges of the blind sit past the glass. Measure the drop from the top of the frame to the sill or floor, never from the ceiling.

Every blind carries a 3/4 in side rail gap, so the fabric runs clear of the brackets while the light path stays narrow. On a door, the drop matters more than the width: the fabric has to clear the handle and the floor without dragging.

If the opening falls outside 150, 160 or 170 cm, we build custom roller blinds to your measurement — send width and drop in centimetres, the mount type, and whether the chain should sit left or right. The same applies to blinds for windows in older buildings where nothing is square and a standard size will simply not sit right.

Room-by-Room Applications

• Bedrooms. The whole point of a blackout blind: a summer dawn, a street lamp and a neighbour's security light dealt with, and the room dark enough to sleep through. An outside mount gives the cleanest edges.
• Home offices and meeting rooms. Drop the blind to desk height to kill screen glare without losing the room, and the opaque face stops the monitor being read from the car park.
• Kitchens and bathrooms. The moisture-proof fabric and wipe-clean face handle steam and splashes, and the clamp mount means nothing is drilled into tile or a sealed splashback.
• Living rooms and lounges. Use the daylight fabric where the room should stay usable in the afternoon, or the blackout fabric where the television wall takes direct sun.
• Balcony, patio and French doors. A tall drop in one piece, fitted above the opening so the door still swings clear — usually the reason people ask for a 170 cm width in the first place.
• Rentals, serviced apartments and student lets. These blackout roller blinds go up and come down without a mark on the wall, which keeps a deposit and a turnaround schedule intact.
• Hotels, clinics and care rooms. One consistent blackout across every room, the same grey or beige on every window, and no light band across the head of the bed.
• Offices with a glazed frontage. A row of window roller blinds in one colour reads as a finished fit-out rather than a patchwork of tenant blinds.

Colour & Finish

The palette is deliberately quiet: white, grey, black, beige, plus a custom colour match when a project needs one. Nothing in the range has a sheen or a print, so a run of these blackout blinds across a facade reads as one continuous surface rather than a set of separate windows.

White disappears into a pale reveal and is the safe choice for a rental or a resale. Grey sits well against aluminium frames and modern joinery. Black gives a strong, graphic line on a large opening and hides the fabric edges most effectively when the blind is only part-dropped. Beige warms up older plaster and timber without going yellow under sunlight.

The face is matte and the reverse carries the silver coating, which is visible from outside — worth knowing on a building where the external appearance matters. Rolled up, the headrail is slim and the fabric sits close to the glass, so the window keeps its proportions instead of gaining a heavy box above it.

For multi-room work, order the whole floor in one batch so the fabric comes from a single production run. If you need to match an earlier order, send a sample and ask us to confirm the match before anything is cut.

Production Process

1. Place order. You send width, drop, fabric, colour, rail profile, bracket type and the chain side. We send the specification back for confirmation before anything is cut — the cheapest mistake to fix is the one caught at this stage.
2. Stock up. Fabric, tube, rail profiles and brackets are drawn from stock held for the roller line, so a repeat order and a first order are made the same way.
3. Select material. Fabric comes off the roll against the confirmed specification; custom roller blinds are cut from the same stock rolls as standard sizes, only to a different measurement.
4. Cut fabric and rails. The fabric is cut square to the drop, and the top rail and bottom bar are cut to the exact width with the hem matched to the rail profile.
5. Assembly. Tube, fabric, bottom bar, clutch and chain go together on the bench, and the clamp brackets are matched to the rail and packed with the blind.
6. Inspection. Each blind is dropped and rolled back up, checked for squareness, chain travel and fabric tension before it is signed off.
7. Packaging. Carton with a PP bag as standard, or a PET box when the blind is going onto a store shelf; mail-box packing is available for smaller drops.
8. Delivery. Consolidated for sea freight, air freight or express courier, depending on the schedule and the order size.
9. As a window blinds supplier working with builders, e-commerce sellers and chain store groups, we run the same eight steps whether the order is a single room or a full building — inspection does not get skipped because a job is small.

Ordering & Delivery

• What to send with an order. Width, drop, mount type, fabric (blackout or daylight), colour, rail profile, bracket type and the side you want the chain on. A photo of the window frame helps more than a description.
• Minimum order quantity. Confirmed per size and finish — send your sizes to your sales contact and they will come back with the figure for that exact specification.
• Samples. Ask your sales contact about sample availability and the current terms before you commit a project to a fabric.
• Packing. Carton with a PP bag as the standard, a PET box when the blind is going onto a store shelf, or a mail box for smaller drops.
• Shipping. Sea freight for full orders, air freight when the schedule is tight, and express courier for samples and small replacement quantities.
• One-stop export service. Documentation, consolidation and booking are handled from our side, so the order arrives as one shipment rather than several.
• Rush orders. If a handover date is close, say so when you enquire — small rush runs are possible and the earlier we know, the more room there is to fit them in.
• Full-project orders. For a whole building of black out roller blinds, send the window schedule and we will come back with one specification covering every opening.
• Factory visits. You are welcome to see the line running in Dongguan or at our Anhui base before placing a project order — useful if you are choosing a window blinds supplier for a long programme of work. Arrange a time with your sales contact.

Tool-Free Easy Installation

All the mounting hardware you need comes in the box — brackets, screws and an instruction manual — and the fixings suit most standard windows. You can fit the blind as an inside mount tucked into the window recess or as an outside mount sitting over the frame, whichever suits the space. Either way, expect to have it up in about 15 minutes, with no professional help and no specialist skills required.

Sleek & Versatile Style

The collection comes in more than 12 neutral colors, including white, gray, beige and black, and in a spread of widths from 24" to 72". Clean minimalist lines let the blind settle into modern, industrial, rustic or traditional rooms, so it blends with your furniture and walls instead of competing with them.
