Abstract
A shade channel system and method provide interchangeability of use with a zippered shade and a regular or blackout shade, together with improved efficiency of installation. A guide channel accepts a shade and is configured with a tensioning mechanism to allow the guide channel to be retained at varying depths within a base channel. The system is suitable for providing polished, uniform looks throughout a room and allowing for use of standard-sized shades by allowing the guide channel to be placed at an adjustable depth within a base channel. Existing channels may be utilized, or new base channels may be coupled to existing mullions.
