- Prepare the door: Mortise the door to a width of 7/16" and the desired depth to accommodate the seal.
- Remove gasket: Slide the gasket material out from the end of the metal retainer.
- Install retainer: Place the metal retainer into the mortised section of the door and secure it using the provided screws.
- Replace gasket: Slide the gasket material back into the metal retainer.
- Adjust: Ensure the seal is adjusted so it does not prevent the door from closing or latching properly.
