Rectangle to Round Insert Adapter Boot

The Rectangle to Round Insert Adapter Boot allows you to make connections between round flex liners to inserts and stoves with rectangle or oval exhaust openings. The heavy gauge cast iron boot can withstand extreme temperatures. The collar is angled back toward the damper. The low profile design will clear most fireplace openings. Our adapter boot features a collar and base that can be separated to adjust to 10 degree or 30 degree tilt to accommodate most dampers. It is recommended that you use a chimney liner Appliance Connector to connect the liner to the insert boot and refractory cement to seal the connection between the boot and the stove.
