If your wood stove or outdoor boiler door isn't sealing tight, you're losing heat and efficiency. This 1-inch diameter fiberglass rope gasket is the fix. It's braided for durability and handles high temps without burning up. The 9-foot length is enough for most standard doors. Fits many brands: Central Boiler, Heat Master, WoodMaster, Shaver, and more. Installation is easy: scrape off the old gasket, apply a bead of high-temperature silicone (sold separately) into the channel, press the rope in, and let it cure. Makes your door airtight again, so you burn less wood and get more heat. Also works for furnace doors, fireplaces, or any high-heat sealing need. Keeps smoke where it belongs—inside the stove! A simple, cheap repair that can make a big difference in your heating bill. Keep some on hand for maintenance season.
