The trap consists of two U profiles joined by a soft PVC board specially treated with a protective coat, allowing perfect articulation. This is all one piece, so it is completely air tight. . There is no termal bridge and can not be altered by oxidation.
The PVC board is placed in such a way that always forces the flap to open, so the strings are always taut. This makes the copilot SERWALL hatches suitable for their use in an emergency since they opened naturally.
