DuraVent DuraTech LDC Trim Collar for Round Support Box: covers the gap around your ceiling support
The DuraVent DuraTech LDC Trim Collar for Round Support Box is a square metal trim plate with a round opening. It hides the ceiling cutout around the round support box. The plate is Galvalume steel painted black and attaches with four wood screws. Choose a 10, 12, 14, or 16 inch size to match your chimney and box. Only the collar is included. DuraTech LDC is DuraVent’s large diameter chimney, an insulated double wall pipe made in 10 to 24 inch sizes for big fireplaces, furnaces, and boilers.
The chimney uses heavier steel than the smaller DuraTech line. Its stainless steel inner wall and Galvalume or stainless outer wall surround a packed 1 inch insulation blanket. That makes a 12 inch chimney 14 inches across on the outside. Match this collar only with DuraTech LDC parts, not 5 to 8 inch DuraTech, DuraChimney II, or another brand.
