Stop valve designed to work in conjunction with any 3" piping, hose or duct inlet/outlets. This valve allows you to vent without exposure to outside air/critters when the fan is not in use. Quick release model updates:This model completely eliminates the need for a threaded stem and substantially reduces operation time and headache, it further eliminates the need for any supports for the bottom and top overhangs (although you may choose to use minimal additional supports for the inner top ‘T inlet’ overhang). Outlet (male): 2.9" ODInlet (female): 3" ID Assembly:Simply Insert the valve disk through the inlet end of the valve housing, and thread the stem onto the valve disk. For the threaded variant see:For a compatible wall mounted duct adapter see: If you like this design, don't forget to like, boost and follow for future updates. Enjoy!
