10" x 46" Rectangular Fireplace Flue Plug, Double-Layer Felt Chimney Draft Stopper for Unused Fireplaces, Fits Rectangular Flue Openings up to 9" x 45", Telescopic Removal Rod

Keep your home more comfortable during the off-season with this 10" x 46" rectangular fireplace flue plug. Designed for rectangular flue openings up to 9" x 45", the plug is slightly oversized to create a snug compression fit that helps reduce drafts, outside odors, dust, and debris entering through an unused fireplace flue. The double-layer felt construction provides a thicker, denser seal, while the telescopic metal removal rod makes it easier to insert, position, and remove when needed. The rod adjusts from 16" to 60" for added convenience, and the felt can be trimmed slightly for compatible rectangular openings. Important: This product is for unused fireplaces only. Always remove the plug before lighting a fire. Not for actively vented gas fireplaces, active fire use, or round flues. Please measure the inside flue opening before ordering to ensure proper fit.
