When space is at a premium in your laundry room, fit your dryer duct with an Imperial 4-in Space Saving Quick-Connect Elbow. At 90 degrees, this compact connector elbow minimizes the gap between your clothes dryer and the wall behind it to just 4-in, giving you more space to move. Quick and easy to install, it requires no clamps, tape or other tools to keep it secure, also making it easy to remove for cleaning. The elbow is designed for use with both flexible and semi-rigid ducting, and is multi-purpose to connect the duct to a dryer exhaust port. With this quick-connect elbow, you can create more space in your laundry room while protecting your duct from becoming crushed between the wall and dryer.
