The SR1800 Series 6" (inch) Riser: This accessory complements our primary SR1800 solar attic fan. This modular adapter was created to allow the user to add six inches between the base and hood (fan/solar module). This additional clearance allows for installation on tile roofs, sod roofs, snowy areas, and other industrial applications where more clearance is required.
NOTE: The product offered is ONLY the 6" extension collar.
For the fans themselves, check out our SR1800 solar attic ventilation fans.
