T-RAIL
More uniformity.
Less bulk.
An alternative to conventional ZIP technology, for a smoother fabric surface and more compact rolling.
A different edge, new possibilities
Innovation lies
in the details
On conventional ZIP screens, the ZIP band welded along the fabric edges holds the fabric in the side guides. T-RAIL performs the same function using a strip that changes shape: it lies flat on the roller tube and takes on a T-shaped profile inside the guide. This design offers significant benefits:
Fewer wrinkles,
a smoother surface
Reduces the formation of wrinkles near the side guides, improving the uniformity of the fabric.
Smooth,
even rolling
The edge stays flat against the fabric, preventing a buildup of thickness as the screen rolls up.
More fabric,
same cassette
With the same cassette size, more fabric can be rolled up, allowing taller screens.
Flat during rolling
As the fabric rolls up, the T-RAIL strip flattens and follows the fabric without creating extra thickness at the joint. The result is smoother, more compact rolling.
T-shaped during travel
As the fabric unwinds, the guide gives the strip its T shape. The profile holds the fabric within the side guide, supporting smooth movement and secure retention in windy conditions.
How it works
One strip,
two shapes
T-RAIL’s geometry adapts to the two phases of screen operation, combining compact rolling with secure fabric retention.
THE COMPARISON
See the difference
Wrinkles may form near the side guides.
Fewer wrinkles and a more uniform fabric surface.
Rolling onto the roller tube
The ZIP edge can create a buildup of thickness.
The edge stays flat for more even rolling.
MORE ROOM FOR FABRIC
Same cassette,
taller screen
Reducing the thickness of the edge makes better use of the available space. With the same cassette dimensions, T-RAIL allows more fabric to be rolled up.
A practical advantage even with smaller cassettes, allowing taller screens while keeping overall dimensions compact.
The achievable heights depend on the model, fabric and configuration. Check the available dimensions with our team.
THE EDGE, LAYER BY LAYER
Conventional ZIP
With T-RAIL
AN OPTION ACROSS THE ENTIRE ZIP RANGE
Your ZIP model
with T-RAIL
T-RAIL is available as an alternative to conventional ZIP on every ZIP model in the Soles range, without exception.
This technology costs more than a standard ZIP system and is therefore available at an additional charge, to be assessed when configuring the screen.
The T-RAIL system is also suitable for solar shading fabrics, including PVC-coated and PVC-free materials.
Quick answers
Is T-RAIL added to the ZIP system, or does it replace it?
T-RAIL replaces conventional ZIP as the system that retains the fabric along its sides. It is an alternative configuration, not an additional component installed alongside ZIP.
Is T-RAIL standard equipment?
No. T-RAIL is an optional feature available at an additional charge on all Soles ZIP models. It must be specified when configuring the screen..
How much taller can the screen be?
The benefit depends on the cassette, roller tube, fabric and chosen configuration. There is no single height increase that applies to every model. Our team can check the achievable dimensions for your project.
Can this technology also be used in other applications?
Yes. T-RAIL can also be used on roof-window blinds and insect screens. To check availability on products other than Soles ZIP models, please contact our team.
