Can you tell what it is yet?

What you see in the picture is a rubber strip. We fit this to the floor under a garage door on occasions when water is getting into the garage.

They work particularly well with sectional doors and roller doors where the rubber on the garage door itself meets with the rubber on the floor.

They are relatively inexpensive to have fitted and they come in a variety of different heights. We use a company called Weather Stop.

They are designed to be driven over and they have a yellow line on them as a health and safety reminder!
