Professional Roman Blind Child-Safe Breakaway Mechanism Kit – 1:1 Ratio
This Professional Roman blind child-safe breakaway mechanism kit provides a 1:1 direct-drive control for compatible Professional-type Roman blind headrails.
The breakaway mechanism is designed so that the operating chain releases from the control unit if excessive force is applied, providing an integral child-safety feature without the need for a conventional wall-mounted chain tensioner.
Supplied as a useful replacement or upgrade kit.
What This Part Does
The control mechanism fits into the end of the Roman blind headrail and operates the square drive rod connected to the cord drums.
The 1:1 ratio provides direct operation, making it particularly suitable for smaller and lighter Roman blinds where geared assistance is not required.
Child-Safe Breakaway Operation
If excessive force is applied to the operating chain, the chain disengages from the control mechanism.
The mechanism can then be reset and the chain refitted.
This integral breakaway design provides a neat child-safe alternative to a conventional control mechanism and wall-mounted chain tensioner.
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.
What’s Included
1 × 1:1 child-safe breakaway control mechanism
1 × Matching end cap
Operating chain is not included and is available separately.
Retrofit Information
This kit can be used to replace a compatible existing breakaway mechanism or to upgrade a compatible Professional-type Roman blind headrail to breakaway operation.
The child-safe mechanism is slightly longer than some conventional Deluxe control mechanisms. When retrofitting it to an existing headrail, the square drive rod may need to be shortened slightly to accommodate the new mechanism.
The mechanism is secured to the square drive rod using a hex key.
