Also called gap seals, cab extenders help to close the gap between the tractor and the trailer. They are often used in cold weather climates to prevent the warm air from the tractor from escaping and the cold air from the trailer from entering. This can help to keep the cab of the tractor warmer and improve fuel efficiency.
Cab extenders are also used to improve safety. When a truck is driving, it is important that the space between the tractor and trailer is as small as possible. This helps to ensure that the truck is stable and less likely to tip over. Cab extenders help to achieve this by making the gap smaller.
There are a variety of different types of cab extenders available on the market. Some are made out of plastic or metal, while others are made out of rubber or foam. It is important to choose the right cab extender for each truck.
