Does anyone know if its possible to buy a roller blind kit that is longer than 240cm? My DIY blackout cloth screen is 270cm wide and I would like to be able to roll it up after use (fixed frame screen is sadly not an option for me ). I've spent ages searching the Internet and 240cm is the largest kit I have found. The alternative I'm thinking of is to to buy a 240cm kit then simply replace the supplied pole with my own longer pole but I'm not sure if that would work. Anyone have any ideas/suggestions? TIA! Josh.
