Rated 1.0 out of 5 by 1 reviewer.
Rated 1.0 out of 5.0 by Not as shown in picture Very deceiving picture, I choose this because of the clean appearance, it arrives by ups and its nothing like picture. The outer shielding is Not tight nor is the insulation, its just good old loose fiberglass insulation around the inner core..outer part is much ,much larger than inner core..Yes it will function well I'm sure, but for my installation I really wanted a clean tight look......not happy October 1, 2013
