Secure Black DL Stove Pipe by Security Chimneys: A Safe and Efficient Choice

Security Chimneys’ Secure Black double-wall (DL) stove pipe stands out as a superior option for all wood stove types. This stove pipe undergoes rigorous testing at temperatures up to 2,100°F and maintains a safe 6-inch clearance from combustible materials. Its remarkable performance is attributed to its innovative design—a double-wall stove connector designed with strategically positioned openings for maximum heat recovery from combustion gases.
