Installing a new wood stove. Need to go through a vaulted ceiling. Went with the Metalbestos ceiling support box (6T-SB), but after opening the box, found this piece to be a little "rough around the edges". (ie, gaps, rivots, no trim ring) What other options are there for going thru the vaulted ceiling? Looking at the Selkirk catalog I found a kit for this application, PCK (pitched ceiling support kit), would this provide a better looking finished product? Any other suggestions, ideas, photos, links etc. Thanks.
