DuraVent DuraTech Trim Collar for Roof Support: black trim that follows your ceiling’s slope
The DuraVent DuraTech Trim Collar for Roof Support is a black painted metal plate that covers the opening around the chimney at the ceiling. It goes with a roof support and follows the ceiling’s slope to hide the gap. DuraTech is DuraVent’s double wall chimney, an insulated pipe with a 1 inch wall that takes over from the stovepipe at the ceiling or wall and runs up past the roof. Its pipe sections twist together to lock, with no screws or bands needed at the joints. A locking band is optional.
Pick the chimney diameter first: 5, 6, 7, or 8 inches. Then choose your ceiling pitch range: 0/12 to 3/12, 4/12 to 6/12, 7/12 to 9/12, or 10/12 to 12/12. Pitch measures inches of rise over 12 inches of horizontal run. Use this only with DuraTech, not DuraPlus, DuraChimney, or another chimney line. Need the matching support? See the DuraVent DuraTech Adjustable Roof Support for the chimney. The DuraVent DuraTech Trim Collar for Roof Support ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
