Hello, thanks for your question and we're sorry for any confusion. This SKU is the 11.5" width product.
Hello, as a static vent (non-powered) this product has 18 square inches per lineal foot of Net Free Area (open area for venting), so depending on how many lineal feet of ridge vent you plan to install, we recommend at least the same amount of total Net Free Area at the soffits/undereave to provide an effective, balanced system. Thank you for your question.
No, only a case of 10.
Hello, please contact your local Home Depot Pro Desk for further information. This product is typically sold in warmer climates that do not require a ridge vent to have a weather filter. Thank you for your question.
