ABSTRACT:
An insert having a peripheral contact surface is received by a roller tube channel to engage a shade fabric. The insert is adjustable to compress the shade fabric within the channel. The insert may include a body having opposite side edges and at least one elongated slot. The insert member may include pivotable prongs or deflectable slot walls adjacent the slots. Pivoting of the prongs or deflection of the slot walls urges the body toward a channel side wall to compress the shade fabric. The insert may, alternatively, include a body having diametrically opposite portions respectively defining a curved outer periphery and a planar outer periphery, the body being wider between the curved portions. The insert is pivotable about an axis to grip the shade fabric between a channel side wall and one of the curved portions of the body.
