To remove our perfect fit wood, metal, roller or pleated blinds, push the small plunger that sits proud within the hole in the perfect fit frame and the frame should just pop out. You will need to do this on all brackets, using a blunt instrument such as a flat screwdriver or key. Please take care when doing so and only do this if you’re competent in DIY.
To remove the perfect fit brackets from the seal, hold the bracket between your Thumb and fore finger, moving the bracket in a slight twisting of clockwise and anti-clockwise direction repeatedly, whilst at the same time pulling the bracket from the seal. Do not move the bracket back and forth.
The whole frame does come out yes if you do the above steps with each bracket.
