Deluxe Roman Blind Control Mechanism – 1:4 Ratio
This Deluxe Roman blind 1:4 control mechanism is a replacement geared control unit for compatible Deluxe-type Roman blind headrails.
The 1:4 geared ratio reduces the effort required to raise the blind, making it particularly suitable for larger or heavier Roman blinds.
What This Part Does
The control mechanism fits into the end of the Roman blind headrail and drives the square rod connected to the cord drums. Turning the operating chain rotates the drive rod and cord drums, raising or lowering the blind.
1:4 Geared Operation
A 1:4 ratio mechanism provides geared operation rather than direct 1:1 drive.
Requires less effort to raise the blind
Provides slower, more controlled operation
Particularly useful for larger or heavier Roman blinds
Can be used when replacing an existing compatible 1:4 mechanism or when converting a compatible Deluxe system from 1:1 operation
Compatibility
Designed for the Deluxe-type Roman blind headrail, approximately 32mm wide × 36mm high, with an approximately 6mm bottom opening.
This profile is also used by the Hallis Perspectives system.
Roman blind headrails can look very similar, but Deluxe, Professional and Elite components are not automatically interchangeable. Please compare the end profile of your headrail with our Roman Blind Headrail Identification Guide before ordering.
