This protection screws into a wood subflooring to hold it in place and thus cannot be used on sliding doors installed over cement slabs which are commonly used on the west coast. Another option that does work for protecting sliding doors installed on cement slabs is impact-resistant U-board protection. It is a thick heavy weight compressed paper protection that is made from recycled material and is completely reusable. The U-board is placed over the tracks while the door is open and protects sliding door tracks from dirt and grime. As with the plastic protector the Sill Pro keeps the sliding tracks clean and protects the tracks of the door from damage that can interfere with the working operations of the door.
They are known to flake and chip when exposed to sunlight and are often cited for creating more work than the protection provided. These low quality 2 or 3 mil. tapes often leave a sticky adhesive residue on thresholds as the adhesive used in the tapes softens in warm temperatures.

In parts of the country that constantly suffer from hurricanes you will often see a storm shield garage door threshold seal fitted.

Some may even opt for the lighter weight fiberglass composite garage door. These are less common as they do not provide the level of security that the previous two do. They can be lower in cost though. Whichever of the options you opt for you must ensure that you install a good quality garage door threshold seal.
