Secure Black® Double Wall

The Secure Black Double Wall (DL) stove pipe from Security Chimneys is tested to 2100°F and listed as 6” clearance from combustible materials for all types of wood-burning stoves. The double-wall black stove connector features a series of openings, allowing for maximum recovery of heat from flue gases.

A TRADITION OF EXCELLENCE

For over 50 years, Security Chimneys has been an innovator in the venting field and a market leader in North America. Instrumental in the company’s growth has been an ongoing focus on product improvement and the introduction of new, innovative products. The proven Secure Black Double Wall pipe is just one example of this commitment to engineering solutions that outperform.

SAFE, DURABLE, AND EFFICIENT

With the Secure Black® Double Wall (DL) pipe, Security Chimneys has designed a product that has been successfully tested to 2100°F at a 6-inch clearance from combustible materials. This level of safety delivers the peace of mind your customers demand. Temperature rating of 1000°F Max continuous; 1400°F brief forced fired; and 2100°F 30 minutes tested. The inner liner is made of corrosion-resistant stainless steel, helping to deliver better protection of the exterior finish. The outer wall features a series of openings that allow for maximum recovery of heat from the flue gases. In fact, it is almost as efficient as a single wall black pipe.

DESIGNED FOR INSTALLATION EASE

Furthermore, it may be used with all types of stoves and is available in diameters of 6, 7, and 8 inches.

Good quality, but a few issues with the hidden mounts and levelness.
Size: 35x7 2Pcs, Color: Black, Size: 35x7 2Pcs, Color: Black
These are quite nice and also sturdy. Only complaint I have is that I bought a couple of these, and on one of them, only one of them, it was difficult to get the hidden mounts to go into the holes. I think it was probably a manufacturing defect thing. Also, on that particular one, it wasnt as level as the other. Not a show stopper, but if you need a perfectly level type of mounting situation, I would be careful here.
