Buying Guide
What size should I buy?
- Confirm the duct opening size is 6 inches (150 mm) and check inner dimensions if specified. Some covers have a slightly smaller inner size but are still used for 6″ vents.
- Measure both the vent opening and the outer housing to ensure the cover will fit the exterior wall or ceiling cutout.
What materials matter?
- ABS plastic offers lightweight durability and weather resistance, ideal for exterior use and moisture-prone areas.
- Stainless steel provides rust resistance and a premium look, suitable for high-humidity environments or stylish exteriors.
