So it must have been seen as suitable by the firm that initially fitted them. **Q: the shaft on my blind is 4.73mm square, will this fit, or do you have a sidewinder that fits?** A: These parts are specifically designed to be replacements for Hillary’s blinds. If you have a Hillary’s Roman blind, it will fit and work perfectly. I’m afraid I didn’t measure mine before I repaired it, so I can’t tell you if it would fit another type. **Q: Does this mechanism come with chain** A: No chain. I just swapped the undamaged chain from the old one - very easy to do. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect. *by on Reviewed in the United Kingdom 26 November 2025* Very good quality and well made.
