A 1000 deg. F. rope designed for use in forming airtight, compressible seals around stove, fireplace, and furnace doors. Intended to replace hazardous asbestos ropes and other worn sealing materials, particularly in preformed door gasket troughs. Made of the highest quality braided fiberglass, this rope is resilient, pliable, and readily conformable to irregular shapes and corners. To ensure peak operating efficiency, door seal should be replaced on an annual basis.
