Back Flange

 Back flange nail fin

Flange:  back
Coverage: 1.5”
Trim face: 1"
Mounting options: through nail flange or vent wall

 

 

The front flange or nail fin is the black line on this drawing.  It covers 1" of the vent face with hemmed edges and extends 1 1/2" beyond the edge of the vent on the back.  As it is one continuous piece, it then forms the outside of the vent wall and continues to cover 1" of the back.

Tthe vent under cap is the green line.  It is a stabilizer and an internal cover to hold the screen in place.

The outer rail system is the gray line.  It holds the inner rail straight during manufacturing.

The inner rail system is the blue line.  Tthe louvers wrap around the rial for a better vent.

The louver is red on here.  The end of the louver is notched for the rail to slide into and be pop riveted into place.  This also adds a lot of strength to the louvers.
