Installation is a snap! No tools or hose clamps necessary. This piece is best placed directly behind dryer to connect the vent, but can also be used to attach the transition duct to the BetterVent Indoor Dryer Vent without the use of clamps. Made to attach snugly to the hose and your dryer with a secure seal. The flexibility and angle of this connector allows the pieces to fit properly and hug the wall when the appliance is placed against it. This straight snap-on connector piece has dimensions measuring 4 3/4" x 4 3/4" x 4 3/4". Made in USA by Ziggurat Products.
