Nailing fins are set back from the outer edge of the window frame and have fastener holes.
The purpose of nailing fins is to secure the window to the wall sheathing and hold it in place while the shims and screws are being installed. Fins also work in conjunction with flashing and a weather resistant barrier to help prevent water and air infiltration.
