Professional Roman Blind Control Mechanism – 1:4 Ratio
Professional Roman Blind Control Mechanism – 1:4 Ratio
This Professional Roman blind 1:1 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 Direct Operation
The 1:4 ratio mechanism provides direct operation, with the operating chain directly controlling the lifting system. It is particularly suitable for smaller and lighter Roman blinds where geared assistance is not required.
For larger or heavier Roman blinds, our 1:4 geared child-safe version may provide easier operation.
Compatibility
Designed for the Professional-type Roman blind headrail, approximately 33mm wide × 32mm high, with an approximately 9mm bottom opening.
This profile is also used by the Hallis Professional 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.
