<p>The roller shutter or blind for the outside of a window has a flexible member (4) descending from a slot near the roller. Connected near the lower edge of the blind is a double flanged joint (7, 8) attached by means of a cross-bolt. Along the top of the frame along the underside of the support flanges are two flat sealing strips (9, 10) and bolted attachments to enable the blind to be clamped. The strip extends across the full width of the window opening. The sealing strip enables the size of the slot to be adjusted to accommodate the blind.</p> |
