Question : Can you buy extenders for under a queen bed like 80 inches total?
Answer : Yes, you can buy two units and use the extension piece to add an additional 15 inches of length.
Question : I need something longer than 30 inches. Can you use 2 extensions on one vent?

Question : Does anyone know how tall the vent is? It needs to fit under a bookcase that is 1.25 inches off the floor. Will this fit under the bookcase?
Answer : If you are only using one piece of the vent extender (less than 17 inches of extension), the height of the extender is about 1.28 inches. It may fit under the bookcase, but it will be a tight fit. If you are using both pieces, it will likely not fit if your bookcase is strictly 1.25 inches off the floor.

Question : How tall is the opening in the vent? I am placing it on a vent in my living room with carpet. Due to the carpet, will it be too fluffy for airflow?
Answer : The plastic vent cover is about 1.5-2" tall. The effectiveness of airflow may depend on the length and thickness of the carpet pile. Tacking it down to the carpet with staples may help ensure proper airflow.
