When a chimney run has to dodge a joist, the FST30 firestop thimble maintains the required clearance to combustibles through an offset penetration. It keeps the framing safely separated from the pipe while the 30-degree offset routes the chimney around the obstruction.
- Maintains required clearance to combustibles at an offset penetration
- Used when the chimney offsets through a joist rather than passing straight through
- Pairs with the 30-degree offset and return elbow set
- For Superior 8DM standard and 8HT high-temperature double-wall wood-burning chimney
| Model | FST30 (catalog F0912) |
