TR85 Extra-Wide Indoor Guided Roller Blind
A Compact Guided Roller Blind for Indoor Openings Over 4 Metres Wide
The NewHoo TR85 is a motorized indoor guided roller blind developed for wide windows, glass walls and commercial openings where a conventional free-hanging blind may not provide the required width, fabric guidance or installation flexibility.
Its compact 85 × 100 mm headbox integrates a fabric support structure and balancing mechanism. Combined with a 35 mm tubular motor, 43 mm roller tube and T-band side guidance, the system can be configured for a single blind width exceeding 4 metres.
TR85 is particularly suitable for projects that want to cover a wide indoor opening with one continuous blind instead of dividing the space into several narrow units.
Designed for the Challenges of Extra-Wide Indoor Blinds
Standard roller blinds are often suitable for regular windows, but wider openings create additional requirements.
Project teams must consider whether the headbox can fit within the available space, whether the fabric can remain guided during operation, how the system will be installed and whether dividing the opening into several blinds will create unwanted gaps.
TR85 addresses these concerns through a compact headbox, internal fabric support, built-in balancing mechanism, motorized operation and T-band side guidance.
The result is a more practical system for large indoor openings where width, appearance and installation efficiency are all important.
Cover Wide Openings with Fewer Blind Divisions
TR85 can be configured for a single blind width exceeding 4 metres.
For suitable projects, this allows one continuous fabric panel to cover a large window or glazed opening instead of using several separate blinds.
Reducing the number of blind divisions can provide:
Fewer visible gaps between adjacent fabrics
A cleaner appearance across the opening
Fewer separate headboxes and blind units
More consistent operation across one wide area
A simpler overall shading layout
The final available width must be confirmed according to the blind height, selected fabric, motor configuration and installation conditions.
Compact 85 × 100 mm Headbox
Extra-wide roller blinds often require larger structural components, which can make the headbox difficult to fit within a ceiling recess or coordinate with surrounding interior finishes.
TR85 uses an 85 × 100 mm headbox that integrates the main operating and support components within a relatively compact profile.
This makes the system suitable for projects where the blind needs to coordinate with:
Window frames
Ceiling recesses
Curtain-wall structures
Interior wall finishes
Limited upper installation spaces
The compact enclosure helps reduce the visual impact of the system while still supporting an extra-wide blind configuration.
Integrated Fabric Support Structure
TR85 includes an internal fabric support structure designed for wide-span operation.
As the width of a roller blind increases, maintaining consistent fabric winding becomes more demanding. The integrated support structure helps support the fabric inside the system as it rolls and unrolls.
For project buyers, this feature provides a more suitable structural basis for extra-wide indoor applications than a conventional unsupported roller blind.
The actual fabric performance will still depend on the blind dimensions, fabric specification and installation accuracy.
Built-In Balancing Mechanism
A balancing mechanism is integrated inside the TR85 headbox.
The balancer works together with the motor, roller tube and fabric support structure to assist the movement of the wide fabric panel.
Instead of relying only on the tubular motor, TR85 uses an integrated system in which the main components are configured to support extra-wide operation.
This is particularly important for projects where the blind width and fabric weight exceed those of a standard indoor roller shade.
T-Band Side-Guided Structure
TR85 is not a conventional free-hanging roller blind.
A T-shaped retaining band is connected along both sides of the fabric and travels inside the guide rails as the blind opens and closes.
This side-guided structure helps:
Keep the fabric edges aligned with the guide rails
Reduce uncontrolled sideways fabric movement
Maintain a more controlled operating path
Improve the appearance of the lowered blind
Provide more consistent edge positioning across a wide opening
The T-band system should be described separately from a conventional zipper-edge guide. Although both belong to the wider category of guided roller blinds, TR85 specifically uses a T-band retaining structure.
TR85 is primarily designed for indoor applications and should not be presented as an outdoor wind-rated blind unless verified test data is available for the exact configuration.
Motorized Operation for Large Indoor Blinds
TR85 uses a 35 mm tubular motor together with a 43 mm roller tube.
Motorized operation is especially useful for wide blinds because the user does not need to manually raise or lower a large fabric panel.
Depending on the project requirements, the system may be configured with suitable control options such as:
Wall switch control
Remote control
Centralized group control
Compatible building automation control
Available motors, control systems and electrical requirements should be confirmed before production.
Install the Blind Body First, Then the Side Rails
One of the practical advantages of TR85 is its installation sequence.
The main blind assembly can be installed first. After the headbox and blind body are positioned, the side guide rails can be aligned and secured separately.
This approach helps solve a common installation problem with extra-wide blinds: lifting and aligning the headbox and both side rails as one complete assembly can be difficult on site.
Installing the components separately allows the installer to:
Handle the blind body and guide rails independently
Establish the final headbox position first
Align the side rails according to the installed blind
Make on-site adjustments more conveniently
Check the main blind before completing the rail installation
This installation method is particularly useful for large openings where small positioning differences may affect the final alignment.
Top-Mount and Side-Mount Options
TR85 supports both top mounting and side mounting.
Top Mounting
Top mounting is suitable when the headbox can be fixed to a ceiling, lintel, window recess or other horizontal structural surface.
This installation method is commonly used when the blind needs to sit close to the upper edge of the window or remain partially concealed within a recess.
Side Mounting
Side mounting is suitable when the system needs to be fixed between walls, window frames or vertical structural surfaces.
It provides an alternative when overhead fixing is unavailable or when the blind must fit inside a defined opening.
Before installation, the fixing surface should be checked to ensure it can support the complete blind system. Fixing hardware should be selected according to the ceiling, wall or frame material.

When Should You Choose TR85?
TR85 may be a suitable solution when:
The indoor opening is too wide for a conventional roller blind
The project aims to reduce the number of fabric divisions
A single blind width exceeding 4 metres is required
The available space requires a compact headbox
Side-guided fabric movement is preferred
Motorized operation is required
The installer needs to mount the blind body before the side rails
Both top-mount and side-mount options are needed
Another system should be considered when the blind will be exposed to outdoor weather, requires a verified wind-resistance rating or needs a manual operating method.
Information Required for Project Evaluation
To evaluate whether TR85 is suitable for a project, provide:
Finished opening width and height
Required installation position
Top-mount or side-mount preference
Installation surface and structural conditions
Fabric type, colour and openness requirement
Required motor control method
Quantity of blinds
Project drawings or on-site photographs
Space restrictions around the headbox and side rails
The system should not be selected based on width alone. Blind height, fabric weight, installation accuracy and control requirements also affect the final configuration.
FAQ?
Can one TR85 blind exceed 4 metres in width?
Yes. TR85 is designed for extra-wide indoor applications, and a single blind width can exceed 4 metres.
The final approved width depends on the blind height, fabric selection, motor configuration and installation conditions.
Is TR85 a ZIP-guided roller blind?
TR85 uses a T-band side-guided structure rather than a conventional zipper-edge structure.
It belongs to the broader guided roller blind category, but the retaining method should be accurately described as T-band guidance.
Is TR85 suitable for outdoor installation?
TR85 is primarily designed for indoor use.
For outdoor openings exposed to wind and weather, a dedicated outdoor ZIP-guided roller blind with an appropriate wind-resistance specification should be selected.
Can TR85 be installed inside a window recess?
Yes. Depending on the available fixing surfaces and dimensions, the system can be top-mounted or side-mounted inside the opening.
Why are the side rails installed after the blind body?
Installing the blind body first allows the installer to confirm the final headbox position before aligning and securing the guide rails.
This makes installation and adjustment more manageable on extra-wide openings.
Does every project support a width exceeding 4 metres?
No. The width capability must be evaluated for each project.
The final size depends on the blind height, fabric specification, motor selection, mounting method and site conditions.
