Hi how are the perfect fit blinds attached to the window? Are they drilled or do they clip in?

Hello,

Many thanks for your question,

The perfect fit blinds are installed with brackets that fit into the beading of the window,

please find below link to our measuring and fitting guide which shows how they are installed and how to check your windows are compatible and how to measure for the blinds if they are.
