Need better control over your HVAC airflow? These 6-inch manual dampers are simple but super useful. Made from galvanized steel, they're tough, rust-resistant, and handle high temps. One end fits into a 6-inch duct (about 6 inches diameter), the other end is slightly smaller (about 5.87 inches) for a snug connection. You slide it into your ductwork and secure it with screws, then seal with tape or sealant to prevent leaks. By adjusting the internal flap, you can direct airflow to different branches, balancing your system for more comfort and efficiency. Great for range hoods, dryer vents, exhaust fans, or any residential/commercial HVAC application. They don't provide a complete seal – they're for balancing, not shutting off airflow entirely. Comes in a handy 2-pack. An easy upgrade for DIYers or pros!
