Product review (5 stars): Whirlpool Gas Dryer Side Vent WGD92
Fantastic. Great quality sheet metal, thick and solid. Includes several lengths, caps for the old hole, grommet, so if you have a Whirlpool with knockouts for side vents, you can use any of them. I used it on a WGD92 HEFWO Unit, but it will probably fit any Whirlpool that can do side vents.
