ABSTRACT:
A device for correcting skew in roll-up retractable coverings for architectural openings includes a friction device positioned within the head rail for movement between releasably fixed positions and disposed for engagement with the fabric of the covering to regulate the rate at which the fabric is wrapped about a roller in the covering at selected locations along the length of the roller to correct for any inherent skew in the covering.
