CAVALIERE Range Hood Chimney Extension for 10' to12' Foot Kitchen Ceilings - Fits Wall Mount Series CAV-B02-30/ SV218B2-30-LED

old houses require the additional length to reach the ceiling, I have had to buy several of these for old 11 ft ceiling in homes I restore, it just seems a bit costly for a piece of stainless with a couple of 90 degree bends in it.
