In the world of venting solutions, one name stands above the rest - DuraVent. With an unwavering commitment to engineering excellence, DuraVent has carved out a niche as the industry leader, delivering a comprehensive range of venting products renowned for their innovation, safety, and professional quality. As a dedicated champion of the HVAC and Hearth markets, DuraVent understands the importance of keeping your spaces both cozy and safe. And with the DuraTech Trim Collar for Round Support Box, they've taken another significant step towards achieving that goal.

DuraTech is the embodiment of perfection when it comes to venting solutions. This remarkable product boasts a dual-wall construction with refractory insulation expertly encased between its layers. The outcome? Unparalleled safety and performance that will put your mind at ease. With this unique design, the outer wall of your chimney remains cool to the touch, even when your fireplace is blazing, ensuring maximum safety. Simultaneously, it maintains higher flue gas temperatures to optimize draft performance, guaranteeing a cozy and efficient heating experience.

What truly sets the DuraTech Trim Collar apart is its inner wall, which is a remarkable 25% thicker than those of competitive chimneys. This additional thickness is not merely a detail but an essential safety feature. It eliminates the need for locking bands or mechanical fasteners, simplifying installation and enhancing safety. Your peace of mind is our priority.

If you're concerned about extreme conditions, DuraTech has already conquered those worries. The 10"-24" DuraTech chimney is rigorously tested and certified for continuous operation at temperatures of up to 1000°F. Even in the harshest conditions, it maintains its structural integrity, withstanding one hour at a scorching 1400°F and enduring ten minutes at a blistering 1700°F, all in accordance with the demanding UL 103 test standard.


  • Impeccable Concealment: The DuraTech Trim Collar is your secret weapon for hiding the unsightly gap between your chimney pipe and ceiling cut-out. Say goodbye to unsightly exposed areas and enjoy a polished, finished look in your living space.

  • Built to Last: Crafted with precision, this trim collar is constructed from Galvalume and painted black, ensuring both durability and aesthetic appeal. It's a lasting investment for your home.

  • Safe Clearance: The DuraTech Trim Collar ensures a 2" clearance to combustible materials, offering an added layer of security. You can enjoy your hearth with peace of mind, knowing that safety is at the forefront.

  • Certified Excellence: It's not just us; the DuraTech Trim Collar has earned its stripes, being c-UL-us listed to UL 103 and ULC S604 (MH7399). It's a mark of excellence you can trust.
