Abstract: A wheel chock and method for stopping the rotation of a wheel including a U-shaped member and a pair of downwardly depending flanges, each of the pair of flanges attached to opposite sides of the U-shaped member and extending outwardly therefrom. Each of the flanges has a width shorter than the vertical height of the U-shaped member. While most wheel chocks either move when subject to sufficient horizontal force or are permanently fixed to a surface, this chock is designed with a removable lag assembly to secure the chock from inadvertent displacement but can be removed and transported for wheel security at another destination.

Abstract: Garages and other large buildings having wide overhead doors are subject to increased maintenance and cleaning as a result of the unwanted entry of moisture, dead leaves and other debris which are often blown along the surface of the yard or driveway and into the door opening. A rigid threshold section with a pair of flanges is directly mounted below using a lag assembly and receives the overhead door therein to block and deter leaves and other debris from entering the opening when the door is being opened or closed. Cars and other vehicles can drive over the threshold section without difficulty or damage thereto due to its shape and rigidity. Multiple threshold sections can be joined to form a threshold of sufficient length for a particular door width in either a permanent or temporary manner.
