Vent Cover

When I open the fir downs above the tubs, for storage, I need to make the doors as large as possible since the storage will be deep.   The original bathroom exhaust vent cover will obstruct the doors when opened, so I decided I need to make some that are closer to flush with the ceiling.    

Old Vent Cover

One of the vent covers in situ.   It sticks out a little over an inch.



Here is the bottom side, laying on a table.  



The top side, you can see the air slot around the edge and the two hooks, center right and left to hold the spring that retains it to the fan housing.  



One of the spring holders.  



The spring catches, the ring is captured by the hook on the cover, the ears at the other end go in a narrow slot in the fan housing.
