4" x 48" Flex Aluminum Duct

Part Number: 448
Created specifically for the models 4D and 3D Dryerbox for downward exhaust direction but with very innovative custom ends. This is only available from our store and features an adaptive coupling on one end and a special expanded end on the other that better secures these sensitive connections. It measures 4" in diameter by 48" long (when stretched out) and 19" when compressed. This product has been custom cut to best fit the Down-box configurations. Any longer than 19" compressed may prevent the dryer from being located right against the wall. This aluminum flex product is almost always specified by the appliance manufacturer and offers the most efficient flexible transition hose. 

Please note: This is too long to be used with the up-style boxes (425, 500, 400 and 350) but is a no brainer to purchase along with the 4D or 3D models. Use part number 439 for 425 and 350 Dryerboxes.
