A pelmet is a rubberised flap or strip fitted along the top edge of the curtain on a curtainsider trailer or rigid body. It bridges the gap between the curtain and the roof rail to form a weather-resistant seal.
The primary function of a pelmet is to prevent rainwater and road spray from entering the load space during transit. It also helps maintain internal cleanliness, especially important when transporting dry goods or palletised freight.
Pelmets are usually fixed to the roof cant rail and overlap the top of the curtain. They are made from flexible rubber or PVC materials that can withstand frequent movement and exposure to the elements.
