Starting in March 2013, Hart & Cooley, Inc. will be updating the Hart & Cooley brand ECSD and ECSDD step-down diffusers.
On the ECSD (with the slide damper), the 1” gaps near the damper will be covered up. In addition, extra screw holes will be added to the larger sized diffusers, the center core will no longer have a margin along the edge and the outer core will cover more of the outer margin. The SKU numbers of these items will be changed.
