Black Window Roller Blinds

a blind consisting of a length of fabric rolled around a pole and fitted to the top of a window.Within the blinds industry, a 'blackout blind' is a roller blind with opaque fabric housed inside a cassette. The fabric runs within side channels to block out all light around the edges. Most manufacturers call these blinds a 'dim-out blind' as there are very few blinds that will actually guarantee 100% blackout.
