Side channel block light from the side of the shade.  The fabric fits through the middle of the channel, and brushing fully blocks the light. See details here.  Channel purchase quantities are LINEAR FEET of shade height, rounded up to next whole foot.

Color: White powder coated aluminum, light gray brushing.  Black color is available as a special order - please ask us.

CUT length.  Since the channels are extruded aluminum, most customer cut the channel to final length during installation.  We can cut to a specific length when you add this detail to 'Notes to seller" on the cart page.

Order for BOTH sides for full light blocking.  You need 2 pieces, each the height of the shade.  Example:  for a 53" high shade, order 10 feet of side channel (round up to 5 feet each side, then multiple by 2).

FREE shipping when purchased at same time as shades, and shade widths are longer than channel lengths (they fit in same shipment)

SHIPPING CHARGES apply when ordering channels by themselves, or channel lengths are longer than shade widths.  Surcharges apply for lengths >94" and freight charges for lengths > 104". Call for details.
