Abstract
A damper arrangement is described which moves dampers from a location closer to an air source to a boot located adjacent to a ceiling register, grill, or the like, thereby allowing technicians or owners to more readily make adjustments. A substantially flush boot collar mounting preserves leak free flow, and keeps insulation installation simple. An internal adjustment mechanism, such as a loop, avoids the need to pull the ceiling grill from the ceiling. Both insulation and subsequent adjustment are simplified.
