Our commitment to innovation, safety, and professionalism has earned us a reputation that speaks for itself. When it comes to your HVAC and Hearth needs, accept nothing but the best.
The heart of the DuraVent DuraLock Wall Support/Band Assembly lies in our revolutionary DuraLock technology. Experience the satisfaction of a lock-tight connection like never before. As the alignment indicators meet, you’ll feel the ends grasp together, and then, with an audible snap, the connection firmly locks into place. It’s a game-changer in the world of venting, ensuring a secure and reliable connection every time.
Crafted from strong and durable galvanized steel, our outer pipe boasts internal spacing beads that ensure a uniform insulating air space between pipe walls. Each end is die-formed to guarantee uniform sizing, making connections a breeze. In Canada, select lengths are available in galvalume steel outer pipe, offering even more durability and versatility.
Safety is paramount, and the DuraLock Wall Support/Band Assembly embodies this principle. Its double-wall construction, with a pipe within a pipe, provides permanent insulation. This design keeps the inner pipe hot while maintaining the outer pipe’s relative coolness. The result? Quick, robust vent action that minimizes condensation and prevents overheating of nearby enclosure surfaces.
