I bought these sturdy metal roller blind fittings to replace broken plastic ones. They are very good quality and were easy to fit. I am considering replacing all the plastic fittings with these ones.
Good solid metal brackets. The plastic roller mechanism has a spring loaded prong that can be pushed back to allow easy location of the blind into the holding metal brackets. No bending of the brackets to insert blind as in cheap plastic brackets.
Excellent quality, incredibly strong. This will probably last forever. We found that you had to think carefully about how to install these but once you’ve worked it out it’s actually very logical even if some angles of work are a bit tricky!
