77mm Roller Shutter Interlock T Spring – Curtain Hanger
This interlock T spring is a top strap for connecting a compatible 77mm aluminium roller shutter curtain to its barrel. It forms the connection at the top of the curtain so the shutter can wind onto the barrel.
Compare the profile engagement, spring shape, fixing points and barrel connection with the product photographs. The 77mm designation describes the intended shutter profile; it does not establish compatibility with every shutter of that size.
The correct number and spacing of hangers depend on the shutter design and curtain size. Follow the shutter manufacturer's specification when replacing or fitting top straps. Contact us with the existing part's dimensions and photos if you need help identifying a match.
