Everbilt 4 in. Adjustable Solid Aluminum Dryer Duct

The actual center to center is not anywhere close to 45 inches. Extended you might get 35 inches if you go from pipe center to pipe center. The outer measure in functional mode is 40 inches. For a flimsy piece of tin patched together like this, the price is not worth it. The package came smash dented, but luckily the dent missed the duct itself. It is light and easy to install, but I could have made this out of aluminum foil, what a crappy waste of time. These manufacturing fools need to wake up and see that we don't appreciate garbage at high prices. Can't recommend...
