Broan-Nutone® Housing Pack for 1688EF, 1671F, 1688F, E0F50 and E0F70 (damper and 4-inch plastic duct connector included). Project packs are ideal for contractors and builders. With the housing for the fan sold separately from the grille and motor, contractors are able to continue with construction and not have to worry about damaging, losing or storing the product. Once all construction is complete, the purchase of a finish pack (grilles and motor/blower wheels) can be made to add the finishing touches to the room. The 6884EH housing pack consists of 18 housings with 4" duct connectors attached. Pair it with the 1688EF, 1688F, 1671F, E0F50 or E0F70 finished packs to create 4" ducted economy fans.
