WR100-120 Concealed Motorized Roller Blind
Concealed Shading for Medium-to-Large Openings
The NewHoo WR100-120 is a fully motorized windproof roller blind designed for recessed installation inside curtain boxes, ceiling pockets and built-in architectural structures.
Its 100 × 120 mm headbox completely conceals the bottom rail when the blind is retracted, reducing exposed hardware and creating a cleaner interior finish.
A bottom-up plug-in structure allows the roller assembly and headbox cover to be installed from below. This makes the system easier to assemble in enclosed spaces where access from the top or front is limited.
With a 63 mm roller tube, a maximum width of 3.8 metres and support for heights exceeding 3.2 metres subject to project evaluation, WR100-120 is suitable for medium-to-large doors, windows and glazed openings.
What Problems Does WR100-120 Solve?
Concealed roller blinds often create three practical challenges.
First, the bottom rail may remain visible after the blind is raised, affecting the clean appearance expected from a recessed installation.
Second, conventional roller assemblies can be difficult to install inside a completed curtain box, especially when installers can only work from below.
Third, some special fabrics may not remain sufficiently flat when used on larger blinds.
WR100-120 addresses these issues through:
- A bottom rail that retracts completely into the headbox
- Bottom-up plug-in installation of the roller assembly and cover
- A 63 mm roller tube for medium-to-large blind dimensions
- Optional T-band guidance for special fabrics requiring improved flatness
- Fully motorized operation without exposed manual chains
Fully Concealed Bottom Rail
When the blind is raised, the bottom rail is stored completely inside the 100 × 120 mm headbox.
This allows the system to remain visually unobtrusive when not in use and provides a cleaner connection with the ceiling, curtain box or surrounding interior finish.
It is particularly useful for hotels, villas, offices and other projects where exposed blind components would conflict with the architectural design.
Bottom-Up Plug-In Installation
The roller tube assembly and headbox cover can be inserted from below.
This structure is designed for curtain boxes and recessed spaces where top access is difficult or unavailable.
For installers, it means:
- The main components can be fitted through the lower opening
- Less access space is required above the headbox
- Installation inside a curtain box is more manageable
- Inspection and component access are more convenient
- The blind can be coordinated more easily with completed ceiling structures
The curtain-box dimensions, fixing surface and maintenance opening should be confirmed before production.
Motorized Operation
WR100-120 is available as a fully electric system only.
Motorized operation avoids exposed bead chains or crank handles and is better suited to concealed installations and larger blinds.
Depending on the selected motor, the system may support wall switches, remote controls, group control or compatible building automation systems.
Motor type, voltage, wiring position and control method should be confirmed before the ceiling or curtain box is closed.
Optional T-Band Guidance for Special Fabrics
Standard side guidance is suitable for most compatible roller blind fabrics.
For special fabrics with different thickness, coating or edge behaviour, WR100-120 can be configured with a T-band guided structure.
The T-band provides more controlled edge guidance and can help the fabric maintain a flatter appearance when lowered.
This option is recommended when:
- Fabric flatness is a key visual requirement
- The blind uses a non-standard or special fabric
- The selected material requires more stable edge guidance
- The blind is relatively wide or tall
Fabric compatibility should be evaluated before final production.
Technical Specifications
| Model | System Type | Operation | Headbox | Bottom Rail | Roller Tube | Maximum Width | Height Capability | Installation | Guidance |
|---|---|---|---|---|---|---|---|---|---|
| WR100-120 | Concealed windproof roller blind | Motorized only | 100 × 120 mm | Fully concealed in the headbox | 63 mm | Up to 3.8 m | Over 3.2 m, subject to evaluation | Recessed, bottom-up plug-in installation | Standard side guide or optional T-band |
Final dimensions depend on the relationship between width, height, fabric weight, motor selection and installation conditions.
Recommended Applications
WR100-120 is suitable for:
- Curtain-box roller blind installations
- Ceiling-recessed shading systems
- Villas and high-end apartments
- Hotels and commercial interiors
- Office meeting rooms
- Large indoor windows
- Glazed doors and partitions
- Projects requiring minimal exposed hardware
It is best suited to projects where concealed appearance and installation access from below are both important.
When to Choose WR100-120
Choose WR100-120 when the project requires:
- A concealed motorized roller blind
- A fully hidden bottom rail
- Installation inside a curtain box or ceiling recess
- Bottom access for assembly
- A maximum width within 3.8 metres
- A height above 3.2 metres subject to technical evaluation
- Optional T-band guidance for special fabrics
Another system should be considered when manual operation is required, no recessed installation space is available or the opening exceeds the approved configuration.
Project Information Required
To evaluate the correct configuration, provide:
- Finished opening width and height
- Curtain-box or recess dimensions
- Installation section drawing
- Motor and wiring position
- Fabric specification
- Standard guide or T-band requirement
- Control method
- Project photos or architectural drawings
Early confirmation of the recess and wiring conditions helps prevent insufficient installation space and inaccessible components.
Frequently Asked Questions
Can the bottom rail be completely hidden?
Yes. The bottom rail retracts fully into the headbox when the blind is raised.
What is the maximum width?
The maximum system width is 3.8 metres. The final approved size also depends on height, fabric and motor configuration.
Can the blind exceed 3.2 metres in height?
Yes. Heights above 3.2 metres can be evaluated, but the final size must be confirmed according to the complete project configuration.
Why is the system installed from below?
The bottom-up plug-in structure allows installation inside curtain boxes or ceiling recesses where access from above is limited.
When should T-band guidance be selected?
T-band guidance is recommended for compatible special fabrics that require more controlled edge movement and a flatter finished appearance.
Is manual operation available?
No. WR100-120 is designed as a fully motorized system.
