Canadian Cedar timber Venetian blinds are made of natural cedar wood. You can choose from two varied shades, light-medium timber or the medium- dark timber, both have 46mm slats. The darker the timber, the older the tree it is from so you may have more variety of shades in a medium- dark blind as the older trees aren’t as available. The timber is lacquered to protect it against the sun. Swan blinds uses commercial grade head boxes and quality child safe string controls. All cedar blinds come with a 70mm pelmet included. Hold down clips are optional and generally used if the blinds are attached to a door.
