Product description
Made-to-measure cassette roller blind – neat and precise
A cassette roller blind is the tidy version of a roller blind. When it is raised, the fabric disappears completely into a slim aluminium cassette – no visible roll of fabric above the window. You order it in your own size up to 150 cm wide and 200 cm high, made with fabrics and components by erfal.
There are two cassette sizes. Roller blind type S has a particularly compact cassette (46 mm high, 44 mm deep) and is available up to 150 cm wide. Roller blind type M has a slightly larger cassette (57 mm high, 64 mm deep).
Three fabric types: how much light would you like?
In the configurator you choose from over 300 fabrics, grouped by how they handle light:
- Privacy: semi-transparent fabrics. Daylight comes in softly and views from outside are softened. Good for rooms that should stay bright.
- Privacy & glare protection: opaque fabrics that let only a little light through. They take the glare out of the sun, for example at a computer workstation.
- Dimout & blackout: light-proof blackout fabrics for rooms that need to be dark. How dark it actually gets depends on the version – more on that below.
Every fabric is shown with its name and fabric number; tap a swatch to see it enlarged. Colours on screen may differ slightly from the original.
With or without side guides
Without side guides the fabric hangs freely below the cassette. It is slightly narrower than the cassette, so a narrow gap remains on both sides where light comes in. For privacy and glare protection this hardly matters.
With side guides the fabric runs in aluminium rails at the sides (type S 30 × 19 mm, type M 40 × 25 mm). Light from the sides is greatly reduced and the blind darkens the room noticeably better. If you want to darken a bedroom, combine a blackout fabric with side guides. We still do not promise a completely light-tight room: depending on the window and installation, some residual light may remain.
You choose the available colours for cassette and guides in the configurator.
Measuring correctly
You enter the finished outer dimensions of the blind in centimetres, not the fabric size.
- Width: outer width of the cassette. With side guides, measure from the outer edge of one guide to the outer edge of the other.
- Height: from the top of the cassette to the bottom of the bottom bar; with side guides, to the bottom of the guides.
This applies to wall and ceiling mounting alike. The manufacturer's measuring guide is available as a PDF in the configurator and under downloads. If you are unsure, we are happy to check your measurements before production.
Wall or ceiling mounting
In the first step of the configurator you choose whether the blind is fixed to the wall or to the ceiling. There are separate manufacturer fitting instructions for both roller blind types and for the side guides, plus care instructions for the fabric.
Chain operation
The blind is operated with an endless chain. You choose in the configurator whether the chain is on the left or the right. Roller blind type M is also available with a spring-loaded centre pull instead of the chain – from 65 cm to 180 cm wide and only without side guides.
The manufacturer’s safety notice for chain operation is shown directly below this description.

Safety notice for chain operation
Attention – warning by the manufacturer (according to the manufacturer in line with EN 13120):
“Children can get caught in the loops of cords, chains or straps that operate window coverings or they can wrap cords around their necks and strangle thereby. Keep cords, chains and straps out of reach of children to avoid entanglement and strangulation. Move beds, cots and furniture away from window covering operations. Do not tie the cords together. Make sure that the cords don’t twist and form a loop.”
According to erfal, the chain is fixed to the wall with a stationary tensioning device (chain holder) at least 150 cm above the floor. For blinds up to 250 cm high, the chain loop is at most 100 cm long. Please read the manufacturer’s fitting and operating instructions (under downloads) before installation.
Frequently asked questions
How do I measure my cassette roller blind?
Enter the finished outer dimensions in centimetres.
- Width: outer width of the cassette; with side guides, from the outer edge of one guide to the outer edge of the other.
- Height: from the top of the cassette to the bottom of the bottom bar or of the guides.
The manufacturer's measuring guide is available as a PDF. On request we check your measurements before production.
What is the difference between the three fabric types?
- Privacy fabrics are semi-transparent and let light through softly.
- Privacy & glare protection fabrics are opaque and let little light through.
- Dimout & blackout fabrics are light-proof.
Will a blackout fabric make the room completely dark?
No light comes through the fabric itself. Without side guides, however, it is slightly narrower than the cassette, so light enters at the sides. With side guides this is greatly reduced. A completely light-tight room is still not guaranteed. For bedrooms we recommend the version with guides.
Roller blind type S or type M – what is the difference?
Type S has the more compact cassette (46 mm high, 44 mm deep) and is available up to 150 cm wide. Type M has a larger cassette (57 mm high, 64 mm deep).
Can I fit the blind without drilling?
The blind is designed for wall or ceiling mounting. Clamp or adhesive mounting is not available for this model. Please contact us if your situation is special.
Where do you deliver and what does shipping cost?
We deliver within Germany, and shipping is free. The current delivery time is shown next to the price.
