Decorative trim collar that covers the gap where a 3" Type B gas vent pipe passes through a ceiling, wall, or floor. Used with the DuraVent BV round Type B gas vent system to give the penetration a clean, finished appearance.

• Fits DuraVent 3" Type B (BV) round gas vent pipe
• For ceiling, wall, or floor penetrations
• Galvanized steel construction
• Slips over the pipe; no fasteners required
• Decorative use only - the firestop or thimble below provides the actual seal

Tip: Install the collar after the pipe is set through the penetration and after any firestop or attic-insulation shield is in place. Slide it down the pipe until it rests flush against the surface and conceals the cut edge.
