Chimney Flue Plug for 11" x 19" Rectangular Chimney Flue, Fireplace Draft Stopper, Energy-Saving Chimney Damper, Blocks Odors & Debris

This chimney draft stopper is designed to fit snugly into the narrow part of the chimney above the fireplace, for use when the fire is out and the central heating is on. It prevents warm air from escaping up the chimney, reducing heat loss and saving energy throughout the day. Made of high-grade, fireproof felt with a retractable metal handle, the draught excluder fits securely in the chimney throat or flue. Simply pull it out before lighting a fire and replace it once the fireplace has completely cooled. Easy to use and reusable, this chimney draft stopper keeps your home warmer by stopping heat loss and blocking cold air, while still allowing minimal airflow to prevent dampness. It helps lower heating bills, minimize wind noise, and stop debris from falling into your hearth.

• This fireplace draft blocker measures 12" x 20" and is designed with 3 sewn-in loops, allowing you to easily trim it to fit flues measuring 11" x 19" or smaller. For a secure and effective seal, make sure the fireplace damper is slightly larger than the flue opening.
• High-grade, fire-resistant felt material: Made of premium fire-resistant felt, this fireplace flue blocker blocks air flow up and down the chimney to prevent cold drafts in winter and keep rooms cooler in summer. It helps reduce energy bills while sealing and insulating the fireplace or wood stove. The dense mat design effectively blocks drafts, odors, noise, and debris from entering your home through the chimney.
• Equipped with a special telescopic pole: To make it more convenient to use, this fireplace cold air blocker is equipped with a telescopic metal pole, which can be freely extended and retracted. The shortest can be contracted to 16 inches, and the longest can be extended up to 60 inches, allowing the fireplace plug to be fixed in the ideal position.
• Easy to install and remove: This chimney draft blocker compresses to fit flues of all shapes and sizes without leaving any gaps, which helps prevent heat loss more effectively. No more pillows or other fabric fireplace covers; simply insert the draft stopper just above the firebox. When you're ready to use your fireplace, the fireplace flue plug can be easily removed with the help of a metal shrink bar.
• Important: This fireplace damper replacement cannot be used with active vented gas log sets. The chimney flue blocker is designed to be installed in the narrow section above the fireplace and should only be used when the fire is completely out.
